hi. i'm a university student in south korea and i'm trying to make a MFC model like this video. before asking something to you, thank you for such a helpful video like this! and i want to ask what is the exact role of the salt bridge and is there enough micro organisim(anaerobe) and organic compounds to be disassembled and take electrons out of them in mud?
The salt bridge maintains a neutral charge in both the anode and cathode solutions just like in any other galvanic cell. Without the salt bridge, the movement of electrons would be halted prematurely.
I don't know the exact name but it is kind of a magnetic stirrer The capsule/tablet like thing she put in is magnetic and you can see her pushing some buttons which spins the table and mixes the salt
I dont get why did used a salt for for me looks brine solution in sludgy paste so it will do the salt may do the trick only I mean it will do salt will make ion that will generate power
Hello, sir. I am a sophomore at Korea College. I am contacting you because I saw your video while looking for it on TH-cam because I was designing an experiment related to microbial fuel cells this time and there was not enough data to make it myself in Korea. I'm leaving it because I was wondering if you still have the materials needed for the experiment and the file written about the experiment process, I hope to get that as an email. Thank you.
hi, for my final year project, i used mudwatt setup (single chamber), for substrate, i only used paddy soil. however it took about 2-3weeks to light up the led. and i also made dual chamber setup, i used potassium ferricyanide as catholyte, the voltage i got was quite high for a 250ml setup, about 300mV
In the experiment we conducted, mud succeeded and water failed. Since the BOD and COD of mud and water were the same, I wonder why you chose mud over wastewater when you think the stickiness of mud influenced your success.
0.4 V is not "an energy". And why are you attaching a 9 V battery to the microbial fuel cell? Are you doing electrolysis? That's absolutely not what a microbial fuel cell is intended for.
Good stuff, thanks for sharing :) Would be even easier using graphite felt for anode/cathode and all in a single container.
excellent animation and explanation
very good project ..
how many hours you kept mud ..before reaching voltage
very interesting, however doesn't the air pump use more electricity that is produced by the fuel cell?
TheLastLogicalOne yes, but instead a watter pump you can use your mouth and do it totally free of energy.
lol
You can replace the sludge with your shit to get more power....

Can I ask something, Do the saltbridge can increase the system resistance?
@@4_andikoputrapratamak.670 yes salt bridge have higher resistance , instead you can use PEM
How to make salt bridge?
good jobe
What did you add to the distilled water after adding salt??
I don't know the exact name but it is kind of a magnetic stirrer
The capsule/tablet like thing she put in is magnetic and you can see her pushing some buttons which spins the table and mixes the salt
Did you heat the water in the end, what was that bubbling all about?
transfer of charges i guess.
I think its oxygen from aquarium bubbler
In return, chemically bound oxygen can be dosed.
what are your experimental treatment ?
how did u make salt bridge
Hi, I am currently conducting a plant microbial fuel cell and I have get no current but only the voltage, what do yo think is my problem
Obviously, your circuit is opened.
what kind of electrode is used in anode n cathode?
Thank you Cindy

So did you get the mail?

I'm an Mphil Chemistry student and interested to work on the fuel cell. Could you guys guide me how to take start to work on H fuel cell.
does the water need to be the same amount as the sludge?
what is the material for the electrodes that you used ? thanks
Theresia Cecylia i guess cupper and zink can be used
What are the possible choices of materials that can be used as electrodes?
Can anyone please help me out
What's PEM made of?
How can I prepare salt bridge please guide me
Hello may I know what is the name of the battery and the setup of the bulb that you used?
What is the purpose of water in the aerobic chamber(Cathode)?
The oxygen in water at cathode will attract the electron produced by electrogen bacteria
What institution are you from?
Did you guys use a proton exchange membrane?
+zixoi they used the salt bridge as a PEM
Cheers dude
Salt bridge is used as a proton exchange membrane.
we can top soil
What is the name of the bacteria in the muck?
Alexia Alvarez i guess cyanobacteria probably
Anaerobic bacteria are used to make microbial fuel cells, the bottom of water areas like this are typically good for anaerobic growth.
electroactive bacteria
May i ask you something, why you add the water In the Cathode? Thankyou
And for what?
In the experiment we conducted, mud succeeded and water failed. Since the BOD and COD of mud and water were the same, I wonder why you chose mud over wastewater when you think the stickiness of mud influenced your success.
Bacteria can create energy in through the water
0,4V of energy?! u cereals bro?
