    Abstract: The fuel processing system of the present invention supplies a flow of H2-r?ch reformate to a water gas shift membrane reactor, comprising a water gas shift reaction region and a permeate region, separated by an H2-separat?on membrane H2 formed over a catalyst in the reaction region selectively passes through the H2-separat?on membrane to the permeate region for delivery to a use point (such as the fuel cell of a fuel cell power plant) A sweep gas, preferably steam, removes the H2 from the permeate region The direction of sweep gas flow relative to the reformate flow is controlled for H2-separat?on performance and is used to determine the loading of the catalyst in the reaction region Coolant, thermal and/or pressure control subsystems of the fuel cell power plant may be integrated with the fuel processing system

    Abstract: A fuel system for an energy conversion device includes a deoxygenator system with a multitude of flow impingement elements which are interleaved t o provide a fuel channel with intricate two-dimensional flow characteristics. The flow impingement elements break up the boundary layers and enhance the transport of oxygen from the core of the of the fuel flow within the fuel channel to the oxygen permeable membrane surfaces by directing the fuel flow in a direction normal to the oxygen permeable membrane. The rapid mixing of the relatively rich oxygen co re of the fuel with the relatively oxygen-poor flow near the oxygen permeable membrane enhances the overall removal rate of oxygen from the fuel. Because this process can be accomplished in fuel channels of relatively larger flow areas while maintaining laminar flow, the pressure drop sustained is relatively low.

    Abstract: An example of a stable electrode structure is to use a gradient electrode that employs large platinum particle catalyst in the close proximity to the membrane supported on conventional carbon and small platinum particles in the section of the electrode closer to a GDL supported on a stabilized carbon. Some electrode parameters that contribute to electrode performance stability and reduced change in ECA are platinum-to-carbon ratio, size of platinum particles in various parts of the electrode, use of other stable catalysts instead of large particle size platinum (alloy, etc), depth of each gradient sublayer. Another example of a stable electrode structure is to use a mixture of platinum particle sizes on a carbon support, such as using platinum particles that may be 6 nanometers and 3 nanometers. A conductive support is typically one or more of the carbon blacks.
