Abstract: An air manager system (10) for a metal-air cell (20) having an air cathode (28) is provided to control air and moisture admitted to the cathode. The air manager system optimizes the use of ambient air and reactant air utilized by a metal-air cell by recirculating (40) the reactant air and admitting (46) only a sufficient amount of oxygen from the ambient air to generate the necessary output for the battery. The present invention also provides a method of recirculating the ambient air while admitting only an amount of ambient air sufficient to replace oxygen that has been used by the cell during operation. The present invention also provides an oxygen supply (42) control circuit which increases or decreases the oxygen available to the metal-air cell based on load demand so as to provide further moisture control. The oxygen control circuit also adjusts the air inlet valve (47) to an optimum setting based upon the particular mode of operation of the load. The invention further provides a cathode plenum (39) having an inlet (42) and outlet (47) and a plurality of baffles (68) defining a nonlinear path, essentially covering the entire surface area of the cathode (28), for the air to flow from the inlet to the outlet in a turbulent manner.

Abstract translation: 提供一种用于具有空气阴极（28）的金属空气电池（20）的空气管理器系统（10），以控制进入阴极的空气和水分。 空气管理系统通过循环（40）反应物空气并且（46）仅从环境空气中吸收足够量的氧气来优化由金属空气电池利用的环境空气和反应物空气的使用，以产生必要的输出 电池。 本发明还提供了一种循环环境空气的方法，同时仅允许一定量的环境空气足以替代在操作期间由电池使用的氧气。 本发明还提供一种供氧（42）控制电路，其根据负载需求增加或减少金属 - 空气电池可用的氧气，从而提供进一步的湿度控制。 氧气控制电路还基于负载的特定操作模式将进气阀（47）调整到最佳设定。 本发明还提供一种具有入口（42）和出口（47）的阴极增压室（39）和限定非线性路径的多个挡板（68），其基本上覆盖阴极（28）的整个表面区域，用于空气 以湍流的方式从入口流出到出口。
