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.

摘要： A fuel cell stack that includes a gas diffusion media for the end cells in the stack that has less of an intrusion into the flow field channels of the end cells that the other cells, so as to increase the flow rate through the flow channels in the end cells relative to the flow rate through the flow channels in the other cells. A different diffusion media can be used in the end cells than the nominal cells, where the end cell diffusion media has less of a channel intrusion as a result of diffusion media characteristics. Also, the same diffusion media could be used in the end cells as the nominal cells, but the end cell diffusion media layers could be thinner than the nominal cell diffusion media layers. Further, a higher amount of pre-compression can be used for the diffusion media in the end cells.

摘要： A gradient of ionomeric material is generated, disposed, or otherwise provided in an electrode suitable for use in a fuel cell. The ionomer concentration, e.g., with respect to the carbon content of the catalyst layer (e.g., expressed as a ratio), is greatest in the area closest to the membrane, e.g., of the fuel cell (e.g., the membrane side), and is decreased in the area furthest from the membrane (e.g., the gas side). By way of another non-limiting example, the ionomer gradient can be formed such that the concentration (or the ratio if expressed in relation to the carbon content of the catalyst layer) can gradually, as opposed to rapidly, decrease as the distance away from the membrane increases.

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.
