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.
