Abstract
Improved water distribution can be obtained within the cells of a fuel cell series stack by maintaining a suitable temperature difference between the cathode and anode sides of each cell in the stack during shutdown. This can be accomplished by thermally insulating the 'hot' end and sides of the stack and by providing a thermal mass adjacent to the 'hot' end.
