Metal-air fuel cell battery device and system with selectively activatable cathode and anode elements

摘要

A novel battery construction including a plurality of discharging cells formed by a cathode structure having plurality of relatively small cathode elements on a cathode support structure, and an anode structure having one or more anode-contacting elements on an anode-contacting element support plate. Each discharging cell can be independently activated (i.e. enabled) using a transistor-based power switching element operated under the control of a switching controller. The novel battery construction may also include a plurality of recharging cells, spatially arranged with the plurality of discharging cells.
