摘要： A metal current collecting substrate for an air cathode in an electrochemical metal air cell is provided for, wherein the substrate is hardened by one of the steps of sandblasting, shotblasting, plastic deformation of the substrate below the recrystallization temperature range of the metal thereof, and heating the substrate to above the transformation temperature of the metal thereof followed by quenching the substrate below the transformation temperature of the metal thereof. Catalytically active materials, most preferably a mixture of carbon and manganese dioxide, are pressed or otherwise disposed upon the hardened substrate. The substrate is capable of being connected to electrical circuitry. Most preferably, the substrate is a metal screen that has been hardened, roughened and pitted by sandblasting before the catalytically active materials are disposed thereupon, and before the substrate is incorporated into an electrochemical metal air cell.

摘要： A system and method are provided for rapidly evaluating electrochemical components such as catalysts, electrodes, electrolyte, and membranes that delivers a high degree of accuracy and requires minimal materials costs. In one embodiment, the system may comprise a detachable electrochemical cell for housing an electrochemical reaction. The cell may comprise an anode chamber and a cathode chamber separated by an ion-diffusion membrane and an electrically conductive current collector in electrochemical communication with the cell. The reaction cell includes an outlet port in the cell to permit the removal of product gasses, and ports to permit the flow of electrolyte through said cell. The system further comprises means, for example, a reciprocating piston, for sealing the reaction cell to the system to prevent exposure of the electrochemical reaction to the ambient environment, where the cell and adjacent components may be sealed by, for example, gaskets, that permit rapid separation.

摘要： This invention pertains to metal-air electrochemical cells wherein one or more air entry ports is located in the bottom of the cathode can, to provide for entry of oxygen-rich air into the cathode can, where the oxygen partcicpates in the chemical reaction whereby the cell produces electrical energy. In this invention, multiple small air entry ports are provided. Generally, the use of multiple ports distributed over the bottom of the cathode can, opposite the reaction surface of the cathode assembly, while not increasing the overall open area of the ports, results in an increase in the ratio of the cell limiting current to the rate at which moisture is lost from the cell. Accordingly, moisture loss as a function of electrical energy produced, is less.

摘要： An improved metal-air button cell is provided. The cell is comprised of the following components: a conductive metal can, a cathode assembly in the can, a conductive metal cover, and a separator between the cathode assembly, wherein the metal cover and separator provide borders of a space in which an anode material can be placed. The improvement is that the amount of anode material is not sufficient to fill the space provided for it, and, wherein, the anode material is positioned against the separator and a void exists between the cover and the anode material.
