Abstract

In a PEM-type fuel cell, explicit coolant conduits (79) are provided that follow the reactant gas flowpaths on either side of undulate MEA layers (70) and are interspersed with planar portions of the separator layers (72) for flow of cooling fluid so as to remove heat from the fuel cell. These coolant conduits can eliminate the need for separate layers for coolant conduits and the need for coolant conduits that pass in the stack dimension through the MEA layers.
