How do fuel cells generate electricity mcq
WebA fuel cell is a device that generates electricity by a chemical reaction. Every fuel cell has two electrodes called, respectively, the anode and cathode. The reactions that produce electricity take place at the electrodes. WebMuch like a battery, a fuel cell produces electricity through an electrochemical reaction, which generates electricity without any combustion. Unlike batteries, fuel cells don’t wear …
How do fuel cells generate electricity mcq
Did you know?
WebFuel cells typically generate electricity using hydrogen and emit only water and heat. For polymer electrolyte membrane (PEM) fuel cells, hydrogen is fed into one side of the fuel cell, and oxygen is fed into the other. Hydrogen ions pass through a membrane and react with the oxygen on the other side to form H2O (or water) and create electricity.
