  1. in normal oxydation reaction of 2 H2 + O2 –> 2 H2O, need initial energy to make 2 H2 –> 4 H+ + 2 e-, and O2 + 2 e- –> 2 O2-, in hydrogen combustion it done by sparking in H2 and air mixture. how it's done in fuelcell? thanks

  2. Hey does anyone know how much a fuel cell system converting hydrogen to electricity weighs?? Im looking to compare a system in a car/vehicle with X amount of electrical output to the weight of different types of batteries and their X electrical output. Any graphs of such online? Thanks!

  3. Excellent explanation. a bit less expressive though. Stress on the important aspects while you describe.

  4. If you're reading from a script you might as well turn it into subtitles so the native folk can 'ear whjat chu saiyan', boay.

  5. by the time we use this, why shouldn't we have enough solar power to do even more than this?

  6. THANK YOU FOR YOUR INTENTION TO SHARE. YOUR THICK ACCENT APPEARS TO LOSE YOUR AUDIENCE. SLOW ANNUNCIATION OF THE ENGLISH LANGUAGE MAY BEHOVE YOUR EFFORTS TO COMMUNICATE. PRACTICE MAKES PERFECT. NAMASTE.

  7. The point of fuel cells is simply that you can refill them fast – you cannot do that with batteries, which is the main critic about electric cars. Our "greenest" way of producing controlable electricity (for whatever purpose) is actually nucelar power. Our cheapest way is oil. Uran and oil doesnt have any impact on nature by extracting it (wind does, solar does, water does).

    So as long as we do not cover the moon in photovoltaic or have mastered fusion power, nuclear power will be the greenest form of energy. Live with it

  8. i cant understand your english, PLEASE redo this video AGAIN.. and speak slower & more "english-like".. thank you
    i could not understand at all.. like every 3 words sounded like english words
    and turning on CC captions.. that doesnt even understand you, pretty funny tho what it says

  9. 1). why electron can not pass through that barrier?
    2). what this barrier is made of?
    3). H and O are gasses so how they can be like solid electrode as you show?

  10. lam very interesting with your explanation. i hope you making video about direct methanol fuel Cell and explain it about transport phenomena, mass transfer and energy transfer, energy activity and enthalpy… lam very clear with your explanation

  11. Why does it have to combine with the oxygen when it's at the other side? The electric current had already been made, so why can't the biproduct be just regular H2 which can then be reused? Or is the oxygen used to "attract" the hydrogen through the barrier? In which case I'm wondering what forces makes it attract through so many barriers?

  12. its very easy understanding not feeling bored and easily gets into mind….. specially way the lecturer uses the example of boys and girls…………………..

  13. This idiot doing this video doesn't know the difference between water and hydrogen peroxide… What a douche bag!!!! It's a wonder why he has as many subscribers as he does… But of course the world is full of idiots.

  14. I have a question: At first there's H2 and O2. When they get together, they produce H2O. As you can see, the end result is 2 particles of Hydrogen and just 1 of Oxygen when at first, there were 2 as well… What happens to the other molecule of Oxygen present at first?

  15. Thank you so much for this video, best explanation on fuel cells. I am doing a project on fuel cells and this helped me understand so much better. Thank u again.
