Can anyone explain how a hydrogen fuel cell works? And also what reaction happens at each electrode?
(I'm taking IGCSE & if anyone can spare the time to write a detailed explanation I would be more than grateful!)

Answer:
A fuel cell works by passing hydrogen through the anode of a fuel cell and oxygen through the cathode. ... At the cathode, the protons, electrons, and oxygen combine to produce water molecules. Due to their high efficiency, fuel cells are very clean, with their only by-products being electricity, excess heat, and water.
Sorry I only know the first question
