초록

A fuel cell having an optimized flow space for the passage of hydrogen gas across the surface of an anode. The invention prevents destructive oxidation of the anode by preventing the buildup of locally high levels of oxygen. The anode surface itself may be shaped in lateral plan to follow the natural contours of gas flow to eliminate hydrogen stagnation areas on the anode surface. Alternatively, the anode surface or the cathode surface may be coated in regions of anode stagnation to prevent the fuel cell reactions from occurring in those regions. Alterna...
