INTERNAL COOLING ARRANGEMENT FOR UNDULATE MEA FUEL CELL STACK

摘要

In a PEM-type fuel cell, coolant conduits (79) are provided that follow the reactant gas flowpaths on either side of the MEA (70) and are formed in the interface between adjacent contacting separator layers (72) of consecutive fuel cells in the stack. These coolant conduits can eliminate the need for coolant conduits that pass in the stack dimension through the MEA layers.
