Abstract: An electric power generation system includes a fuel cell stack and a product water pumping system from the stack to pump product water away from the power generation system. A reactant exhaust chamber is coupled to a product water pumping chamber by a drain, and a valve controls the flow of water through the drain. An oxidant exhaust inlet provides an oxidant exhaust flow to the reactant exhaust chamber from the stack, while an oxidant exhaust outlet discharges oxidant exhaust from the reactant exhaust chamber. A pump fluid inlet provides a pump fluid flow to product water pumping chamber from the stack to pump collected product water out of the product water pumping chamber via a product water outlet. The pump fluid flow can take the form of a fuel stream or by a purge discharge containing fuel.

Abstract: A fuel cell system includes a fuel cell stack, a battery, and a control system. A power circuit couples the fuel cell system selectively between the fuel cell stack and the battery. The power circuit includes a battery supply switch responsive to a voltage across the fuel cell stack, and a stack supply switch responsive to an operating state of the fuel cell system. The battery supply switch uncouples the battery from an on-board power supply when a voltage across the fuel cell stack exceeds a first threshold voltage and couples the battery to the on-board power supply when the fuel cell stack voltage is less than a second threshold voltage. The stack supply switch couples power the fuel cell stack to the on-board power supply when in a running state. A diode-OR circuit couples the source with the highest potential to the on-board power supply.
