Hydrogen Fuel Cells Explained - GCSE Chemistry | kayscience.com
Hydrogen fuel cells produce electricity by reacting hydrogen and oxygen in a fuel cell. The electrodes are made of graphite. Hydrogen gas is supplied to the negative electrode and oxygen gas is supplied to the positive electrode. The electrolyte is alkaline e.g. potassium hydroxide solution which contains dissolved OH- ions. The hydrogen gas diffuses through the graphite electrode and reacts with OH- ions forming water, supplying electrons to the circuit. The oxygen gas diffuses through the graphite electrode, reacting with the hydrogen ions to form hydroxide ions.

    on my word... i did not think this guy had less than 10K subscribers when i saw the video initially. this video was super simple, informative and concise, the explanation was to the point, and anyone who skipped through those questions in the middle seriously missed out on the opportunity to retain the information. well done, my man. btw i have watched like 10s of different studying channels and many of them are amazing, but for this particular topic, this video was one of the best, seriously.

    oh my god thank you so much. i could never understand how hydroxide ions react with hydrogen gas at the negative electrode, but your concise and adept diagrams are truly a godsend

    Thank you very much! I'm doing A-level chem and couldn't understand any A-level explanations for the topic, but you made it seem so easy!

    I've been looking through several videos and this is the first one providing clear explanation of how alkaline fuel cell works. It answers my question of how the water produced in anode suddenly appears in the cathode.

    This is for a basic fuel cell right?

    Hi, how does the reaction of hydrogen and hydroxide ions release electrons?
