Patent ID: 8568933

Claim:
A metal-air fuel cell module capable of supplying electric power to an electrical appliance, said metal-air fuel cell module comprising: a casing configured with an inner accommodating space, and having a top end formed with an opening, and a side surface formed with a plurality of air inlets, said opening and said air inlets being in spatial communication with said inner accommodating space; a cap seat connected detachably to said casing, and having a plug portion that extends downwardly into said inner accommodating space through said opening in said top end of said casing for plugging said opening; an power unit including a conductive gas-diffusion sheet disposed in said casing for covering sealingly said air inlets and permitting air to pass through, an electrolyte solution filled in said inner accommodating space in said casing, and a metal sheet disposed in said inner accommodating space in said casing and mounted detachably to said cap seat; a first electrode plate mounted on said casing and having an end portion that extends into said inner accommodating space in said casing and that is in electrical contact with said gas-diffusion sheet; and a second electrode plate mounted in said cap seat, spaced apart from said first electrode plate, and having an end portion that extends into said inner accommodating space in said casing and that is in electrical contact with said metal sheet; wherein said power unit produces the electrode power in response to electrolytic oxidation and reduction such that the electric power produced by said power unit is supplied to the electrical appliance when the electrical appliance is connected electrically between said first and second electrode plates.
