Abstract:
A metal-air fuel cell battery system for generating electrical power, comprising:a plurality of movable cathode structures, each said movable cathode structure being mounted within a housing to enable movement of said movable cathode structure about a closed path; a supply of metal-fuel tape transportable relative to said movable cathode structures, along a predetermined tape path extending within said housing; an ionically-conductive medium disposed between said plurality of movable cathodes and said metal-fuel tape during system operation, for contacting each said movable cathode structure and said metal-fuel tape being transported over said movable cathode structure, and supporting ionic conduction between said movable cathode structure and said metal-fuel tape during system operation; and a transport mechanism for transporting said plurality of movable cathode structures, said metal-fuel tape and said ionically-conductive medium relative to said housing, wherein each said movable cathode structure is cylindrically shaped and has a hollow center permitting air flow therethrough during system operation.
