Abstract:
A metal-air fuel cell battery system for supplying electrical power across first and second output terminals, the system comprising:a movable cathode structure that is cylindrically shaped and has a hollow center permitting air flow therethrough;a supply of metal-fuel tape transportable relative to said movable cathode structure;an ionically-conductive belt structure transported between said movable cathode structure and at least a portion of said metal-fuel tape, for contacting said movable cathode and said metal-fuel tape and supporting ionic conduction therebetween during system operation; anda transport mechanism includinga first means for transporting said supply of metal-fuel tape relative to said movable cathode structure,a second means for moving said movable cathode structure relative to and at substantially the same velocity as said metal-fuel tape during system operation, anda third means for transporting said ionically-conductive belt structure between said movable cathode structure and said metal-fuel tape during system operation, at substantially the same velocity as said metal-fuel tape during system operation.
