    摘要: An electrochemical cell comprising a gas electrode, including a deposited layer, and a counter electrode. The gas electrode is an electrode that either utilizes a gas as the active material that is reduced by the gas electrode or produces a gas by oxidation at the gas electrode. In a preferred embodiment, the gas electrode is a thin film electrode including a deposited current collector and deposited active material oxidation or reduction layer. A control layer can be disposed between the gas electrode and the counter electrode to control the diffusion of electrolyte into the gas electrode. Methods for making electrochemical cells having gas electrodes are disclosed.

    摘要: An air depolarized battery with an improved sealing member for sealing the air inlet port(s) of the battery before use is disclosed. The sealing member has areas of relatively high and low permeability, with an area of low permeability over at least a portion of an air inlet port. The sealing member may comprise a plurality of layers, where the area of highest permeability includes a portion of the lowest permeability layer that has a higher permeability than a surrounding portion thereof. The rate of flow of air through the low permeability area and into the battery can be easily modified to maintain a desired battery open circuit voltage during battery storage to allow activation of the battery within a short time after removal of the sealing member, while minimizing losses in discharge capacity before use.
