Abstract
A system includes a stack of fuel cell flow plates and a condenser. The stack of fuel cell flow plates include openings to form an inlet manifold passageway and an outlet manifold passageway to communicate a coolant through the stack. The flow plates are capable of transferring thermal energy to the coolant to cause the coolant to change from a liquid state into a gas state. The condenser changes the coolant from the gas state to the liquid state. At least one conduit of the system is connected to communicate the coolant between the condenser and the inlet and outlet manifold passageways.
