Abstract
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.
Claims26
A fuel cell, comprising:
- a membrane electrode assembly (MEA);
- and
- a flow field plate assembly which comprises an anode flow field plate and a cathode flow field plate that said MEA is sealed between said anode and cathode flow field plates, wherein said cathode flow field plate has a flat side and an opposed channel side that said MEA is sandwiched between said anode flow field plate and said flat side of said cathode flow field plate, wherein said cathode flow field plate further has a plurality of flow channels formed at said channel side for enabling fluid flowing along said flow channels to promote electrochemical reaction through said MEA so as to generate electrical energy.
A cathode flow field plate assembly for a fuel cell having a membrane electrode assembly (MEA), comprising:
- a cathode flow field plate having an inner side and an outer side, said inner side of said cathode flow field plate defining a flat side that said flat side of said cathode flow field plate is arranged for facing toward said MEA, said outer side of said cathode flow field plate defining a channel side, said cathode flow field plate further having a plurality of flow channels formed at said channel side for enabling fluid flowing along said flow channels to promote electrochemical reaction through said MEA so as to generate electrical energy.
