    I was pretty sure the reason for the buffer was in case a spark ignited the hydrogen or oxygen, so any combustion can't travel all the way through the system but gets stopped by the water in the buffer.

      You're right, the buffer is also used for that!
      In an upcoming video where I’ll use Hydrogen for heating or cooking, I’ll be using a buffer bottle for safety reasons-you explained its importance very clearly.

      @@jcopfr Oh, I see! This is the first I've heard that it's also used to get the moisture out of the gas though. Sounds a bit counterintuitive to me since it's literally passing through water, but I guess it must be that the droplets of moisture in the hydrogen sort of "stick" to the water as they pass through it?

      @@zeph0shade The Hydrogen gas is of course not wet, but at the Hydrogen outlet, there is also a tiny bit of liquid water that comes out too. This is not a manufacturing defect, I saw in a video showing industrial PEM electrolysers, that they have the same problem!

    Seems pretty comparable to the zinc and hydrochloric acid method in terms of production rate but without the mess and, in the long run, cheaper? Cool beans!

    • @jcopfr
      @jcopfr  11 วันที่ผ่านมา +2

      Yes, you are right !
      For production of small quantities of Hydrogen, the chemical method with hydrochloric acid and zinc is the cheapest.
      However, if Hydrogen production becomes more important, the PEM electrolyzer will become cheaper than the chemical method.

    Proff I just fill balloons with dry 12v battery put salt water inside when charging it produces hydrogen and chlorine! and can filling balloons to fly up !Local products are easy to find.There is mylar or latex!

      That's true, but PEM electrolysers are by far more efficient, and less dangerous. Balloons will also have higher lift when filled with PEM electrolyzers !

      ​@@jcopfr🔴 What Is Islam?
      🔴 Islam is not just another religion.
      🔵 It is the same message preached by Moses, Jesus and Abraham.
      🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
      🔵 It reminds us that since God created us, no one should be worshipped except God alone.
      🔴 It also teaches that God is nothing like a human being or like anything that we can imagine.
      🌍 The concept of God is summarized in the Quran as:
      📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) 📚
      🔴 Becoming a Muslim is not turning your back to Jesus.
      🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

      Salt and hydrogen gas beacuse it sulphuric acid
      If it naoh inside that true it has some oxygen!
      Can you make video about it for me one just need lead acid battery when charging it produces hydrogen gas and the salt.

    I would fear that some of that gas would just leak.

    • @jcopfr
      @jcopfr  9 วันที่ผ่านมา +1

      Hydrogen is such a light gas that it will escape through the roof and the smallest openings (unlike Butane gas which is very heavy and will stay on the ground...). No need to worry!

      Good question!
      I used sewing thread, very light, so light that it was almost negligible (no more than 0.1g)!

      At the end I say that I prefer Mylar balloons while I am filling a latex balloon ! But the text is correct
      In other words: latex balloons cost less than Mylar balloons, but are more fragile, are not reusable and retain Hydrogen for much less time. (That's what I should have said in the video).
