    摘要： In an electrochemical cell a container houses a cathode, an anode, a separator between the cathode and the anode, a negative current collector and a sealing assembly for sealing a terminal end of the separator extending outward from between the cathode and the anode. The sealing assembly seals the terminal end of the separator between a first sealing member in sealing relationship with the first face of the separator terminal end and a second sealing member in sealing relationship with the second face of the separator terminal end. In another embodiment, the sealing assembly seals the terminal end of the separator between the sealing assembly in sealing relationship with the first face of the separator terminal end and at least one of the cathode, the anode and the container in sealing relationship with the second face of the separator terminal end.

    摘要： A zinc/air button cell comprising a cathode casing and an anode casing wherein the anode casing is inserted into the cathode casing. The anode casing is formed of multiclad metal layers, for example nickel/stainless steel/copper. A protective metal is plated onto the exposed peripheral edge of the anode casing. The protective metal is desirably selected from copper, tin, indium, silver, brass, bronze or gold. The application of the protective metal covers the multiclad metals exposed along the peripheral edge surface. The protective metal is also desirably plated onto the portion of the outside surface of the anode casing abutting the insulating material placed between the anode and cathode casing. Application of the protective metal to the anode casing peripheral edge eliminates the potential gradients caused by exposure of the different metals comprising the multiclad material. This reduces the chance of electrolyte leakage which can be promoted by secondary reactions occurring along the anode casing peripheral edge.

    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.
