    摘要: Edge designs, especially for ePTFE-reinforced membranes for proton exchange membrane (PEM) fuel cells, wherein the designs provide a proton barrier at the electrode edge of the PEM fuel cell membrane electrode assembly (MEA) to provide, among other things, resistance to membrane chemical degradation. A portion of the ePTFE layer is imbibed with a proton-impermeable polymer at the electrode edge. The polymer can include, without limitation, B-staged epoxides, B-staged phenolics, hot melt thermoplastics, and/or thermosets or thermoplastics cast from liquid dispersions.

    摘要: A burner type catalytic converter heater composed of an air intake housing having a peripheral mounting flange for universal mounting to an exhaust system upstream of the catalytic converter. A nozzle body is provided having a central portion whereat an orifice delivers atomized fuel and an annular flange portion which interfaces with the air intake housing to define an air intake chamber on an upstream side thereof. A cylindrical combustion chamber housing is provided and a single-stage vortex body is connected to one end of the combustion chamber housing, wherein vanes of the vortex body adjoin a downstream side of the annular flange portion.
