    摘要: A PEM fuel cell system in which an oxidizer is provided and in which the catalyst for the oxidizer is an OMS-2 catalyst and, in particular, an M-OMS-2 catalyst. Preferable catalysts are Co-OMS-2, Cu-OMS-2 and Ag-OMS-2 and, more preferably, Ag-OMS-2. Also, the effectiveness of the oxidizer is enhanced by one or more of the controlled addition of oxidant to the fuel feed and/or oxidizer, controlling the space velocity of the fuel feed and controlling the operating temperature of the oxidizer. A system for regeneration of the M-OMS-2 catalyst and a method of making the catalyst are additionally provided.

    摘要: An end unit for a fuel cell stack is described that contains an integrated heat exchanger for superheating the fuel gas before delivery to the stack. Heat is transferred from the hot cathode outlet stream to the cool fuel inlet stream in a space adjacent the stack's end plate. The end unit is designed as a hollow box forming the shell of the exchanger with the heat exchanger inside. The end unit has openings that allow fuel cell process gas to be taken directly from the stack without requiring piping or ductwork to be attached to thin manifolds. Separate chambers are provided for both the cathode outlet and anode outlet gas, thereby allowing all process connections to be made at one end of the stack. The end unit also features a current collection post that is separated from the end cell of the stack by a multitude of members which provide structural support for the end unit and act to more uniformly collect electrical current than would a single, large current post.

    摘要: A process for providing a variety of light to medium colors of anodized aluminum or aluminum alloy which comprises the steps of anodizing an aluminum or aluminum alloy workpiece in an aqueous strong acid electrolyte solution such as a sulfuric acid solution by application of direct current at a current density of 5 to about 25 amperes per square foot and a temperature of from 55.degree. F. to 90.degree. F. to form on the workpiece a porous anodic oxide film having a thickness of at least about 3 microns; subjecting the resulting anodized workpiece to alternating current at a voltage of about 5 to about 25 volts for about 1 to 25 minutes in an aqueous strong acid electrolyte solution such as a sulfuric acid solution comprising about 1 to 15 volume percent of an organic carboxylic acid containing at least one reactive group in the alpha-position, wherein said reactive group is a hydroxy, amino, keto or carboxyl group; and electrolytically coloring the workpiece. In a preferred embodiment resulting in deepened color tones, including those in the blue to blue-gray and green range, one or more currentless "waiting periods" are maintained at various stages of the process during which essentially no current is applied to the workpiece in the electrolytic solution. In another embodiment, improved color uniformity is obtained by subjecting the workpiece prior to electrolytic coloring to a direct current pre-treatment step. The resulting electrolytically colored aluminum or aluminum alloy is particularly useful for architectural product.
