A method and device for operating a fuel cell system. A recirculation loop coupled to a fuel cell cathode ensures that fluids passing through the cathode are recycled, thereby enabling reaction between residual oxygen in the recycled fluid and fuel that has been introduced into the recirculation loop until substantially all of the oxygen is reacted, leaving a substantially oxygen-free, predominantly nitrogen compound in the cathode and related flowpath. Thereafter, this compound can be redirected to purge the remaining residual hydrogen resident in the f...
What is claimed is: 1. A device comprising: at least one fuel cell comprising an anode, a cathode and a membrane disposed between said anode and cathode; an anode flowpath configured to couple said anode to a fuel source, said anode flowpath having an anode inlet and an anode outlet; a fuel supply valve disposed between said fuel source and said anode; a cathode flowpath configured to couple said cathode to an oxygen source, said cathode flowpath having a cathode inlet and a cathode outlet; and an inert gas generation mechanism comprising: a recirculati...
