COMPACT FUEL CELL STACK WITH UNIFORM DEPTH FLOW FIELDS

摘要

A fuel cell assembly includes two or more plate assemblies (700) stacked together. Each plate assembly includes a membrane electrode assembly (MEA) (702) sandwiched between an anode plate and a cathode plate (716). At least one of the anode plate and the cathode plate has a first flow field (718) on a side facing the MEA and a second flow field on a side facing away from the MEA (702). The first flow field (718) is of a first uniform depth, and the second flow field (720) is of a second uniform depth. In one configuration, the first and second uniform depths are the same.
