ABSTRACT:
A fuel cell system is described having a fuel cell stack including a PEM fuel cell having an anode and a cathode, the fuel cell stack further including an anode outlet and an anode inlet, a hydrogen storage device in communication with the anode inlet and configured to supply a hydrogen gas to the fuel cell stack, and an accumulation reservoir in communication with the anode outlet of the fuel cell stack. The accumulation reservoir is configured to accumulate a quantity of water and an exhaust stream including the hydrogen gas during a purge event and resupply the exhaust stream to the fuel cell stack after the purge event is complete. The accumulation reservoir can be a second fuel cell stack. A method of operating the fuel cell system is also provided.
