Abstract: PROBLEM TO BE SOLVED: To simplify replenishment of a metal air battery with zinc granule by granular anode structure of the battery, and quickly achieve the best battery performance after the zinc granule is replenished in a battery unit.
SOLUTION: In the granular anode of the metal air battery in which a cover of the zinc granule is formed, the cover has a circular structure or a similar circular structure, and an electrolyte is housed in the cover, zinc fuel in addition to the electrolyte is housed in the cover of the zinc granule, a small through hole is formed in the cover, and when the zinc granule is not used, since the diameter of the small through hole is very small, the electrolyte does not effuse, and after the zinc granule is fed to an anode groove of the zinc air battery, the surface of the zinc granule causes chemical reaction with the electrolyte in the anode groove, and the zinc granule starts reaction from the through hole part. The zinc fuel has structure of a plurality of circular arc-shaped flakes, radial zinc pieces, or honeycomb zinc pieces. The zinc granule is formed by making two pieces butt and joining them.

Abstract: PROBLEM TO BE SOLVED: To provide an anode structure of a metal air fuel cell. SOLUTION: The metal air fuel cell is formed into a fin type anode structure, and comprises a current collector piece, a reaction layer, and a reaction supporting layer laid between the current collector piece and the reaction layer, and a a fin structure is formed so as to protrusively extend from the one side of the anode structure. The fin structure has a plurality of hollow parts formed to the fin structure protrusively extending from the one side of the anode structure and an anode plate. Respective fins have horizontal plate extending into nearly horizontal direction, and an open end part slanting downward or folded, formed at the end part of the horizontal plate. This complex sandwich structure can also be formed into wave-shape. COPYRIGHT: (C)2004,JPO
