METAL-AIR FUEL CELL BATTERY SYSTEMS EMPLOYING MOVING ANODE AND CATHODE STRUCTURES

WIPO Patent Application WO1999018620

A3

In an air-metal fuel cell battery system (1), metal-fuel tape (3), an ionically-conductive medium (2) and a cathode structure (4) are transported at substantially the same velocity at the locus of points at which the ionically-conductive medium contains the cathode structure and the metal-fuel tape during discharging and recharging modes of operation. In a first generalized embodiment of the present invention, the ionically-conductive medium is realized as an ionically-conductive belt, which is transported at substantially the same velocity as the metal-fuel tape and cathode structure at the locus of points where they are in contact. In a generalized second embodiment, the ionically-conductive medium is realized as a solid-state gel-like film layer integrated with the metal-fuel tape, which is transported at the same velocity as the cathode structure where they are in contact. In a third generalized embodiment, the ionically-conductive medium is realized as a solid-state film layer integrated with the movable cathode structure, which is transported at substantially the same velocity as the metal-fuel tape where they are in contact. By transporting the movable cathode structure, ionically-conductive medium and metal-fuel tape within the system as described above, generation of frictional forces among these components is minimized during the operation of the system, and damage to these components is reduced.
