Reaction in hydrogen fuel cell
WebJan 1, 2024 · How does a fuel cell make electricity from hydrogen? What happens in a fuel cell is called an electrochemical reaction. It's a chemical reaction, because it involves two chemicals joining together, but it's an … Fuel cells come in many varieties; however, they all work in the same general manner. They are made up of three adjacent segments: the anode, the electrolyte, and the cathode. Two chemical reactions occur at the interfaces of the three different segments. The net result of the two reactions is that fuel is consumed, water or carbon dioxide is created, and an electric current is created, which ca…
