LIQUID COOLED FUEL CELL STACK

摘要

A liquid cooled fuel cell stack is provided which comprises fuel cell modules which comprise one or more membrane electrode assemblies (MEA's); cooling plates which comprise cooling channels; a manifold box communicating with each cooling channel inlet; and a diffuser within the manifold box having a plurality of diffuser outlets distributed evenly with respect to the cooling channel inlets. Typically a two-chamber manifold box is used, to allow counter-flow of coolant in opposite directions in cooling channels on opposite sides of the stack. Typically the stack is insulated around its exterior.
