1. How does a fuel cell work? – Naked Science Scrapb…:

2. Thank you for explaining this to me! It’s a great video! My science teacher
   is hopeless and just says the minimum. Thanks again!:)

3. How does a fuel cell work?

4. No, but I am.

5. Black man… Black man wearing white coat… A book… Interesting logo…
   Use the black man as a resource, whether physical or intellectual, and then
   dress it up in a white coat… Ever wonder what that might do to a
   generation of children, psychologically speaking? Especially over
   centuries?… Talk to somebody who grew up on a reservation, or on a
   ghetto… Why would they “fake” the lunar landing? PsyOps… Psychological
   warfare… Like Iscariot, they covet land, earthly treasure…

6. or how does hydrogen just give away electrons ?

7. Images. Sound. Labels. Colours. Satanists hide behind crosses, and names
   (labels) such as “evangelical”…. Who desires Truth? Jesus said, Seek and
   YE shall find… He did not say that anybody who seeks will find, but he
   said YE shaLL find…. Nor did he say, Ye shaLT find, but Ye SHALL find…
   Shall, Shalt – know the difference? Words matter.

8. You’re*

9. 0.44 – isn’t it a turbine not an engine??

10. Very nice lecture… Pictures, accurate… Also, nice and big… Graven
    images are 3D… Whereas the pictures in this “scrap book” are 2D (not
    graven).

11. Hydrogen is explosive, but its safer when it burns because the diffusivity
    is so high it burns in a column out of the hole it may escape from in a
    matter of seconds. and good luck trying to ignite it when its in a
    compressed container.

12. Has anyone though of taking water molecules and splitting the hydrogen
    atoms from the oxygen atoms, through the process of electrolysis, then
    using the hydrogen and oxygen in a controlled explosion or burn for an
    engine. I realize that electrolysis takes a lot of energy to work but I was
    just throwing up an idea.

13. How is a battery different from a fuel cell? How is a fuel cell different
    from a battery? How are they alike? I think, a fuel cell, is merely a
    battery where the electrolyte is in a dynamic state… And so, rather than
    changing batteries, you change the electrolyte – weighs less… Think of
    the electrolyte as, the fuel.

14. I think the Naked Scientists need a new logo…

15. @Pkthegodpk, you must be thinking about “water powered” cars that
    electrolyse water into hydrogen & oxygen on the go – this video is all
    about the machines that use stored hydrogen and fuel cells – there’s no
    water tank involved. As such, the pressurised hydrogen is certainly
    something we should take into consideration.

16. how does hydrogen form ions without the cathode getting charged?

17. Thanks for the wonderful video!

18. she sounds naked

19. Good

20. Since its extremely inefficient to make the hydrogen in the first place,
    why bother using it to run a car?

21. Hey Anish, I had the same question. From what I understand, the catalysts
    are responsible for stripping the electrode in the anode, and also
    recombining the electron with the water in the cathode. Catalysis looks
    pretty complicated, but it’s where you’d start if you want understand more.

22. Why cant the electrons that had been split up from the Hydrogen Molecule
    pass through the electrolyte???

23. The Word of God is Truth. The words of man… how useful? KJV… Umm,
    Kosher Jew Variant?

24. Steam forces the turbine to rotate, but turbine and ,,engine,, (usually
    synchronous generator) are connected through the gear (or not). Therefore
    if she said turbine it is fine :P

25. Best description I’ve found. Thanks!
