    摘要： The present invention is directed to an electroconductive element within an electrochemical cell that improves water management. The electroconductive element comprises an impermeable electrically conductive element and a porous liquid distribution media disposed along a major surface of the conductive element. Preferably, the liquid distribution media is in direct contact and fluid communication with a fluid distribution layer disposed between the membrane electrode assembly (MEA) and the liquid distribution media, so that liquids are drawn from the MEA through the fluid distribution layer to and through the liquid distribution media. The liquid distribution media transports liquids away from the MEA in the fuel cell. Methods of fabricating and operating fuel cells and electroconductive elements according to the present invention are also contemplated.

    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 method for filling a fuel cell anode supply manifold with hydrogen prior to a start-up operation to facilitate a substantially even hydrogen distribution across the fuel cell is disclosed. The anode supply manifold is in fluid communication with a source of hydrogen. A first valve in fluid communication with the anode supply manifold and a second valve in fluid communication with an anode exhaust manifold are initially in a closed position while hydrogen is supplied to the anode inlet conduit to pressurize the fuel cell stack. The first valve is then opened to purge at least a portion of a fluid from the anode supply manifold to facilitate a filling of the manifold with hydrogen.
