Abstract
A fuel cell stack assembly has a plurality of fuel cells each having a fluid coolant conduit. A coolant feed inlet manifold has a coolant inlet, and the coolant feed inlet manifold is coupled to each fluid coolant conduit for distribution of coolant to each fuel cell. The coolant feed inlet manifold also has a discharge conduit located at one end of the coolant feed inlet manifold. The discharge conduit is configured to discharge excess coolant from the coolant feed inlet manifold. By supplying excess coolant to the coolant feed inlet manifold problems arising due to very low coolant flow rates through the fluid coolant conduits in the fuel cells can be reduced or eliminated.
