PEM Fuel Cell Stack

摘要

A fuel cell includes a cathode flow field plate, an anode flow field plate, and a membrane electrode assembly (MEA) sandwiched between the cathode and anode flow field plate. The cathode flow field plate has a flat side and an opposed channel side that the MEA is sandwiched between the anode flow field plate and the flat side of the cathode flow field plate. The cathode flow field plate further has a plurality of flow channels formed at the channel side for enabling fluid flowing along the flow channels to promote electrochemical reaction through the MEA so as to generate electrical energy.
