Four Components of PEM Fuel Cells
Four Components of PEM Fuel Cells -The anode, also known as the negative electrode of a fuel cell, has multiple functions. It conducts electrons released from hydrogen molecules so that they can be used in external circuits. It has etched channels that can evenly disperse hydrogen gas on the surface of the catalyst. -The cathode (the positive electrode of a fuel cell) is engraved with a channel that [...]
