Summary:An exemplary method of cooling a fuel cell includes directing coolant through a coolant supply channel near at least one reactant flow channel. The coolant supply channel extends from a coolant inlet spaced from a reactant inlet to a coolant outlet. The coolant supply channel includes a first portion starting at the coolant inlet and a second portion near the reactant inlet. The first portion facilitates coolant flow from the coolant inlet directly toward the second portion. The second portion includes a plurality of channel sections that collectively facilitate coolant flow in a plurality of directions along the second portion near the reactant inlet. The coolant supply channel includes a third portion between the second portion and the coolant outlet.
