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 a reduced voltage level across the fuel cell is achieved. Attainment of the reduced voltage level indicates that the recycled fluid is substaintially oxygen-free, yielding an inerting fluid. Thereafter, this compound, followed by air, or air directly c...
The invention claimed is: 1. A method of transiently operating a fuel cell system made up of at least one fuel cell comprising an anode, a cathode, a membrane disposed between said anode and cathode, an anode flowpath fluidly coupled between said anode and a fuel source, a cathode flowpath fluidly coupled between said cathode and an oxygen source and including a recirculation loop with means for selectively introducing fuel therein, a combustor for selectively reacting said selectively introduced fuel with oxygen in said recirculation loop, and an anode...
