Trocciola, J C; Sawyer, R D

A fuel cell system is described adapted to use oxygen-contaminated hydrogen rich fuel gas, the system comprising: (a) an electrolyte matrix; (b) means forming an anode gas space on one side of the electrolyte matrix through which gas space the fuel gas flows from an inlet side of the gas space; (c) means forming a cathode gas space on a side of the electrolyte matrix opposite the one side; (d) a porous anode substrate interposed between the anode gas space and the electrolyte matrix; (e) a porous cathode substrate interposed between the cathode gas space and the electrolyte matrix; (f) a catalyst layer on the cathode substrate on a side thereof facing the electrolyte matrix; and (g) a catalyst layer on the anode substrate on a side thereof facing the electrolyte matrix, the catalyst layer on the anode substrate including an extended strip thereof which extends toward the anode gas space inlet side and which also extends beyond an edge of the catalyst layer on the cathode substrate closest to the anode gas space inlet side.
