ABSTRACT:
A metal air cell comprising a flexible, recloseable, pouch made of a gas-permeable, electrolyte-impermeable, material forming the cathode of the cell, a metal plate anode in the pouch, and spacers physically isolating the anode from the interior of the flexible pouch cathode, the spacers separating the anode and the cathode by a predetermined spacing. A plurality of such cells are preferably stacked into a multicell battery, and compressed in a harness to maintain proper anode-cathode spacing as the anode is consumed. The stack can be incorporated as a replaceable part of a larger power system including a circulatory system for circulating an electrolyte solution through the cells in the stack. A controller controls the circulatory system, particularly during start-up and shut-down, to achieve a fast start up, and an efficient shut down.
