<p>In a PEM-type fuel cell, coolant conduits (40) are provided that follow the reactant gas flowpaths (28) on either side of the MEA layer, either within a space that otherwise would have been part of the reactant gas flowpaths, or nearby. The positioning of the coolant conduits is selected to permit them to remove heat effectively from the fuel cell while lying in relatively space-inefficient portion of the fuel cell, preferably a space that would have, were it not for the presence of the coolant conduits, have been occupied by a relatively space-inefficient portion of the flowpaths. These coolant conduits can eliminate the need for coolant conduits that pass in the stack dimension through the MEA layers.</p> |
