Claim Text:
1. A fuel cell system comprising: a fuel cell stack having a plurality of fuel cells, each of the fuel cells including an electrolyte membrane disposed between an anode and a cathode; an anode supply manifold in fluid communication with the anodes of the fuel cells, the anode supply manifold providing fluid communication between a source of hydrogen and the anodes; an anode inlet conduit providing fluid communication between the source of hydrogen and the anode supply manifold; an anode exhaust manifold in fluid communication with the anodes of the fuel cells and an anode exhaust conduit; a recycle loop fluidly coupling the anode supply manifold and the anode exhaust manifold; and a fan in fluid communication with the anodes of the fuel cells, the fan hingedly coupled to the anode inlet conduit, wherein the fan controls a flow of fluid through the anode supply manifold, through the anodes of the fuel cells, through the exhaust manifold, and back to the anode supply manifold through the recycle loop while the fuel cell system is shutdown.
