    摘要: A catalytic reformer assembly including a reactor comprising a plurality of parallel tubes arranged within a tubular housing. A metal substrate, formed preferably as a metal foam lattice, is brazed to the tubes on both their inside and outside surfaces. A catalytic washcoat is applied to the metal substrate within the tubes, defining thereby the tubes as individual catalytic reforming reactors. Endothermic reforming reactions within the tubes are supported by heat from hot combustor exhaust flowing around the tubes in contact with the augmenting heat transfer metal substrates outside the tubes. Radial temperature gradients are small because of excellent heat transfer across the tube walls, resulting in excellent mechanical stability of the washcoat on the metal substrate. Preferably, the tubes are formed of Inconel 625 and the metal substrate is formed of Fecralloy®, a high temperature alloy having excellent thermal conductivity and oxidation resistance.

    摘要: 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.
