Abstract: A fuel cell assembly (50) having manifold means for providing fuel and air to, and removing spent fuel and air from, flow passageways across the anodes (16) and cathodes (18) in a fuel cell stack. The sizes and proportions of the supply (23',33') and return (27',41') manifolds are optimized, and the total cross-sectional area of the return manifold is about twice the cross-sectional area of the supply manifold. The pressure drop in the manifolds is less than about one-quarter of the total pressure drop across the anode and cathode passageways in the stack, which ratio may be attained by adjusting the thickness of the anode and cathode spacers (38') and/or the size of the chimneys. Widthwise uniformity of flow across the anodes and cathodes is improved by forming each of the manifolds as a plurality of smaller, parallel flow conduits.

Abstract: 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. Alternatively, the gas seals may be formed to cover the anode surface in stagnation regions. Alternatively, the cathode and/or electrolyte may be shaped or thickened to reduce or prevent diffusion of oxygen ions therethrough.
