摘要:
A fuel cell cooling system is provided with a coolant pump for pumping fluid through coolant flow field passages in a fuel cell stack. A pressure control mechanism is provided for maintaining a pressure level within the fuel cell stack for causing a phase change of the coolant within the stack. Allowing the coolant to change phase to a gas inside the stack reduces the amount of coolant needed to cool the fuel cell stack and thereby reduces the energy needed to pump the coolant through the fuel cell stack.
