Abstract
A fuel cell system includes a fuel cell stack, a reservoir, a water management circuit, a cooling circuit and a fan. The fuel cell stack communicates a reactant flow and communicates a water flow. The water management circuit is adapted to remove water from the reactant flow and store the water in the reservoir. The cooling circuit is adapted to generate the water flow that is communicated through the fuel cell stack from the water in the reservoir. The fan controls the amount of water that is removed from the reactant flow to regulate a water level of the reservoir and controls removal of thermal energy from the water flow regulate a temperature of the fuel cell stack.
