    摘要: An electrical shorting device for a fuel cell is provided, wherein the shorting device includes an electrically conductive body and an actuator coupled to the conductive body and adapted to selectively position the body between an electrically conductive and a non-electrically conductive position to selectively provide electrical communication between an anode plate and a cathode plate of the fuel cell. The shorting device facilitates electrical shorting of individual cells during the startup and shutdown of the fuel cell to eliminate the electrical potential across a proton exchange membrane that causes a degradation of a catalyst layer disposed on an a surface of an electrode of the fuel cells.

    摘要: An integrated fuel cell assembly is described. The integrated fuel cell assembly includes a polymer membrane; an anode electrode and a cathode electrode on opposite sides of the polymer membrane; a pair of gas diffusion media on opposite sides of the polymer membrane, the gas diffusion media comprising a microporous layer and a gas diffusion layer, the anode electrode and the cathode electrode positioned between the polymer membrane and the pair of gas diffusion media; a subgasket positioned around a perimeter of one of the gas diffusion media, the subgasket defining an active area inside the perimeter, the subgasket having a layer of thermally activated adhesive thereon; and a bipolar plate sealed to the subgasket by the layer of thermally activated adhesive. Methods of making the integrated fuel cell assembly and assembling fuel cell stacks are also described.
