Abstract

Improved metal-air fuel cell battery systems having metal-fuel realized in the form of substantially planar metal-fuel cards of rigid construction, which can be either manually or automatically inserted within the power generation bay of the system. The power generation bay includes at least one electrically-conductive cathode element supported by a cathode support structure in a stationary position with respect to the cathode support structure, and at least one electrically-conductive anode-contacting element supported by an anode contacting structure in a stationary position with respect to the anode contacting structure. In order to produce a range of output voltages, the power generation bay includes a plurality of cells comprising cathode elements spatially arranged with anode contacting elements, and each metal-fuel card has a plurality of electrically-isolated metal-fuel strips that are spatially arranged with these cells when the metal-fuel card is inserted to the power generation bay. An output voltage configuration subsystem is provided for configuring the voltages produced by the individual cells to produce a desired output. A subsystem is provided for detecting oxide fo…
