Abstract

The temperature of the end cells in a fuel cell stack is controlled by means of auxiliary coolant plates. Outwardly of the end cells in the fuel cell stack there are disposed thermal and electrical insulating plates, and outwardly of the insulating plates there are disposed metal pressure plates. The temperature of the end cells of the stack is controlled by means of auxiliary coolant plates which are connected to the main coolant circulation lines and which are sandwiched between the insulating plates and the pressure plates at each end of the stack. In this way, the outer surface of the insulating plates is kept at substantially the same temperature as the inner surface thereof thus minimizing heat loss across the insulating plates from the end cells in the stack.
