Need help? Ask me your questions here: vespr.org/videos/5130b7d29d534... Using an analogy to hormonal 16 year-old summer campers, we discuss the chemistry and physics of how fuel cells work.
Thanks for the comment. You know, I've thought a lot about this, but I literally get *dozens* of messages every day from students who tell me that my face makes the learning feel more "personal," and that feel they can't learn from other online videos because of the lack of personal connection. Ultimately, it would ideal to have two versions of every video: with and without the head-on shot, and students could choose which is more effective for them. I'll get on it as soon as I have more time!
The ones would be better...as it makes us feel there is someone real explaining to us.... It just makes us understand it better than a video without a face... (like patrickJMT ☺ no offence )
You can separate the water back into hydrogen and oxygen, but to do that, you'll need to use all the energy (plus a little more) that the fuel cell made in the first place. So it can go back and forth, but not as a self-perpetuating energy source.
I really, really appreciate your use of a Boys and Girls Camp analogy. You really dumbed it down for me and now I understand what a fuel cell is and how it works. Thanks for the great vid!
Best chemistry teacher ever! I have been following this channel since 9th Std and am presently in 12th. He really makes the concepts crystal clear... His teaching style is superb!!!
you're so amazing. I wish you were my teacher, I didn't understand this until I watched your video.you deserve SO MUCH MORE CREDIT especially for your creative analogies. great job and thank you so much.
You're amazing at teaching. Thank you for all the work you do for the average kid growing up in this busy world. You deserve many more views, but just know thousands of people across the world are thanking you everyday
I am currently teaching high school physics and chemistry as well, in Malaysia. Sometimes I feel I am making myself trouble to rethink the syllabus in order to present it in the way that is comprehensible by students, and your talk at TED inspire me that I am not alone in this quest. Thank you very much.
This guy has such a good mind at explaining things. I remember when i was researching how batteries worked it took a lot of effort to fininally figure out how they work. I wish this video was out a year ago lol!
I study chemical engineering. My teacher at uni has a very very high knowledge and tries to explain this on a very high level and this was my first time with fuel cell, so thank you for this video I finally understand it.
Great question! That's actually one of the problems with fuel cells. It takes a lot of energy to get those H2 molecules in the first place. Lots of electricity is required to break water apart and make H2--that's how we get most of the H2 used in cars and trucks. The problem? Using H2 in fuel cells is a super clean technology. Getting the H2 in the first place requires energy that may not be generated in particularly green ways.
Nice video. I see this as a great tool for teaching chemistry in middle school, but not so much help to college people. But to break the topic down and explain it as boy-girl posse means that you really understood the stuff, so great job!
The Summer camp reference. 😂😂😂😂😂 P.S. Your teaching method is the BEST! Animated , concise , and.... compendius...... Thank you for your time , and effort 💜
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
Thank you for the great explaination. I understood it really well, even tought another student, before we both had exams yesterday. It went really well. 😄
Thanks so much for explaining that. Your are the only one so far speaking of these all important details - and the Catalyst !!. As with Solar panel "explanations", these thing just happen because the magician said so !
Hello there!!! Thanks for sharing bro..I have a question for you:- I know that the electrolyte made of Polymer membrane sheets, but where can I find them in our daily life or at home, appliances?, and the same for catalyst.. what they look like what they are made of???please give examples of show pictures. Thanks in advance.
It was an amazing explanation. I have a question not entirely connected with this. This is a clean and safe energy, but (mind my lack of knowledge) is getting H2 and O2 molecules safe and clean without any waste too? Can we reverse the water into H2 and O2 to make use of it again?
I understand the separation and movement of the electrons but how are you capturing the energy from their movement. What sort of "work" are they doing during their movement ? Running a generator ? Powering an electrical device directly ?
What is the catalyst made of? What is its chemical component and how is it obtained? Is the catalyst an integral part of the graphite plate or of the membrane that forms the electrolyte? Can you please elaborate? Some of us are interested not only in understanding but also in practical application...
Well,on the cathode side where the oxygen lives,can't we just hold H2 when the protons and the electrons come together? Thus we don't consume the H2 and use it again on the anode side.Is that kinda possible?
I have seen multiple sometimes conflicting accounts of the dimensional size of an electron. While I cannot verify these data, some report the electron to be roughly 4 times the diameter of the proton. If this is correct? If not, I would be interested to know the proper values.
Why make the hydrogen combine with oxygen in the first place? What purpose does oxygen serve? Or is it necessary to sorta "attract" the hydrogen to the other side?
Actually, instead of an electrolyte, it is a proton exchange membrane so here, protons are delivered to the another side of the electrolyte where together it forms water.
The terms "proton exchange membrane" and "polymer electrolyte membrane" are used synonymously. So they are the same thing. And "polymer electrolyte membrane" is often shortened simply to "electrolyte" or "electrolyte membrane."
if water (H2O) is a Covalent compound formed by sharing of electrons, why is it said (in case of fuel cells) that formation of water from hydrogen and oxygen is a redox reaction (transfer of electrons, not sharing). This would make it an ionic compound. Any insights? Note that, the concept of water being formed as a result of redox reaction is highlighted in fuel cells (which is the basic principle of fuel cells - generating electricity by exploiting this transfer of electrons)
***** Hi, I think that by a redox reaction it means that the hydrogen atom is broken down to electrons and protons which means that hydrogen is being reduced because the electrons break away from being an atom and eventually become connected with the oxygen atoms to form water. So I'm sure that when they mentioned 'Redox reactions" they had in mind that the oxygen atoms are causing the hydrogen atoms to break down into protons and electrons through which the oxygen atoms will later combine with to form water. I hope I helped give insight from my understanding. I'm only 15 and in grade 11 so I hope I made sense. Seeing that your question was asked 5 months ago, if you got the answer to it please help me understand as well. Thank you.
Yup, you're exactly right. Electrons are indeed much smaller than protons. It's not a perfect analogy, but I'm just trying to get the very basic concepts across right here. In reality, it's not about size--it's about charge, but I couldn't come up with a good analogy for that. In a fuel cell, that "camp fence" is actually a special membrane that allows positively charged things to pass through, but not negatively charged things. So protons can go right through, but elections cannot.
why we use catalyst..? as the path is covered by electron can also by proton.. why we giving priority to the proton as it move faster than electron...? my simple question is that if electron can take another path then why not proton. is it necessary to use catalyst..?

Jennifer Flores, I agree infinitely.
yes...but its a bit weird to be honest though

I didn't understand a word of the explanation of fuel cells in my book, thanks to you I finally get it!
tyler explains chemistry and natural selection at the same time, you are a genius of your craft tyler

Quite enriching video Tyler. Keep it up
Finally someone that can actually teach!!
I love the way you teaching , your video is really useful and understand
Thanks for your video
The best teach I've ever seen
Great help. Fully understood what i confused about in class. Thank you.
Mr Tyler, that was a brilliant analogy , Thankyou😁😁😁😁😆
Best teacher ever
This teaches me something while im on my brake. Great Job Sir.
your videos are so easy to understand. you made chemistry my favorite subject. thanks. why don't you make more video?
Hey there thanks so much for the efforts u put in remaking the video
Thank you for the great explaination. I understood it really well, even tought another student, before we both had exams yesterday. It went really well. 😄
clever analogy, well done sir!
That was a wonderful explanation! I was wondering if you could give me an analogy for the salt bridge though?
Thank you so much for this tutorial! I have oomph for my Chemistry exam next week!
you know what, this is incredibly awesome!
Thanks so much for explaining that. Your are the only one so far speaking of these all important details - and the Catalyst !!.
As with Solar panel "explanations", these thing just happen because the magician said so !
Nice video! Thanks! Wasn't over keen on the analogy but helped my understanding anyway!
Very nice video. You cleared up a lot of my questions. One other question, what sort of catalyst could decompose a hydrogen atom?
Hello there!!! Thanks for sharing bro..I have a question for you:- I know that the electrolyte made of Polymer membrane sheets, but where can I find them in our daily life or at home, appliances?, and the same for catalyst.. what they look like what they are made of???please give examples of show pictures. Thanks in advance.
Great analogy well done, great help
I love ur vid. Awesome demo and great demonstration XD more plz
Amazing Sir...Best explanation of Hydrogen fuel cell...😊
Many thanks for your geat efforts and simle way for explanation
Brilliant, Sir! That's how education should be done.
Loved the way u explained🥰🥰👍👍👍
Extraordinary stuff!!!!
Thanks for simple demonstration of fuel cell.
Very good explanation, thanks!
Super super easy explaining!! Thx!
Brilliant video, thank you.
Sir is it so easy, the combination between hydrogen and oxygen to give water?this process occur spontaneously?
This is awesome! I'm going to go build a fuel cell now!
Guys can you say me where's part 1 demo is I can't find it
Nice explanation and comparation.
great analogy !
Great video.
Damn, you did it again. I think you got a lot going on in your head with summer camp teens.
Hello Tyler. Pls can u help me with a note on fuel cell for me project. Thanks
Best teacher wow
Can i ask will you be posting new teaching lessons here in youtube?
I really like your videos
for an assignement on school i was thinking of making a fuel cell but instead of platina would i be able to use sulfuric acid as electrolyte
is that the opposite process for electrolytic cell ?
Thank you Tyler
It was an amazing explanation. I have a question not entirely connected with this. This is a clean and safe energy, but (mind my lack of knowledge) is getting H2 and O2 molecules safe and clean without any waste too? Can we reverse the water into H2 and O2 to make use of it again?
i can relate to this analogy thanks Ty
Thanks dude I really understood this
Great video!
Do you have a video that solely deals with electronegativity and covalent bonds?
This legit blew my mind
I understand the separation and movement of the electrons but how are you capturing the energy from their movement. What sort of "work" are they doing during their movement ? Running a generator ? Powering an electrical device directly ?
God bless u Tylerrrrrr!
amazing just loved it ..
Don't change the format of your videos. That's what drew me to them. Your talking to both sides of our brains at once "Brilliant ".

What is the catalyst made of? What is its chemical component and how is it obtained? Is the catalyst an integral part of the graphite plate or of the membrane that forms the electrolyte? Can you please elaborate? Some of us are interested not only in understanding but also in practical application...
Very good explanation ✔ 👍 👌
your topic is good representation rowing
Could you please enable automatic subtitles?
problem with this guy is that he puts all other teacher to shame...
i guess someone has to be the best...

Very good explanation. However i do not really understand why is the oxygen needed on the right hand side ?
nice analogy ^^
Why make the hydrogen combine with oxygen in the first place? What purpose does oxygen serve? Or is it necessary to sorta "attract" the hydrogen to the other side?
Hey, nice speech on TEDtalks!
Please make a video on photoelectrochemical cell and water splitting which are the now a days emerging issues and a solution to green energy
what is the importance of electrolyte ?
Actually, instead of an electrolyte, it is a proton exchange membrane so here, protons are delivered to the another side of the electrolyte where together it forms water.
The terms "proton exchange membrane" and "polymer electrolyte membrane" are used synonymously. So they are the same thing. And "polymer electrolyte membrane" is often shortened simply to "electrolyte" or "electrolyte membrane."
Tyler DeWitt Okay, learnt a new thing. Thank you!
+Juliet i think u might be right can u expl;ain me briefly..?
Where is the other O ? And witch is the energy to produce this process ?
thanks!
