    摘要： The present disclosure generally relates to an on-demand hydrogen gas generation device, suitable for use in a fuel cell, which utilizes water electrolysis, and more particularly galvanic cell corrosion, and/or a chemical hydride reaction, to produce hydrogen gas. The present disclosure additionally relates to such a device that comprises a switching mechanism that has an electrical current passing therethrough and that repeatedly and reversibly moves between a first position and a second position when exposed to pressure differential resulting from hydrogen gas generation, in order to (1) alter the rate at which hydrogen gas is generated, such that hydrogen gas is generated on an as-needed basis for a fuel cell connected thereto, and/or (2) ensure a substantially constant flow of hydrogen gas is released therefrom. The present disclosure additionally or alternatively relates to such an on-demand hydrogen gas generation device that comprises a gas management system designed to maximize the release or evolution of hydrogen gas, and in particular dry hydrogen gas, therefrom once it has been formed, thus maximizing hydrogen gas output. The present disclosure is still further directed to a fuel cell comprising such an on-demand hydrogen gas generation device, and in particular a fuel cell designed for small-scale applications.

    摘要： Collector assemblies and methods of making and using them, and electrochemical cells made with such current collector assemblies, are disclosed. The invention provides a current collector assembly which permits safe, effective venting of pressure in the cell; reduces early activation of venting structures in the current collector assembly; contains fewer piece parts than known structurally-robust current collectors; is easy to implement; and provides superior tolerance to outside impact forces. Current collectors of the invention provide a stiffer, more rigid washer, repositioned closer to the bottom plate at its central region while the washer maintains the traditional function of controlling positioning of the seal body of the current collector assembly. Increasing stiffness, rigidity, and the repositioning of the washer is accomplished by a combination of structurally sculpturing the cross-section of the washer, hardening the temper of the washer, and providing a plateau adjacent the center of the bottom plate. Washer vent holes are relocated away from the central region, the bottom plate being most vulnerable to attack in the central region. Overall, the improved washer provides both support to the seal body against outwardly-directed internal pressures within the cell and support to the bottom plate against inwardly directed impact forces from outside the cell.
