An improved metal-air fuel cell comprising at least one non-consumable gas-diffusion cathode; at least one consumable anode; an aqueous electrolyte containing metal ions; at least one ion-exchange membrane; a housing enclosing said electrolyte, said at least one cathode and said at least one anode; a first unit comprising said housing and said at least one cathode; a second unit comprising said at least one anode and said electrolyte; the improvement wherein said electrolyte is contained within an electrolyte impermeable container, said second unit is adapted to be replaceably, received in sealing engagement within said first unit; and puncture means to effect puncture of said electrolyte impermeable container and allow said electrolyte to make contact between said at least one anode and said at least one cathode when said second unit is received within said first unit. The invention is distinctive in that the current source consists of two units having different functions: a non-replaceable unit representing a body with cathode(s), channels and chambers for intake and distribution of electrolyte and air, and collection of the reaction products and a replaceable unit containing consumable anode(s) and electrolyte. In the non-activated state the non-replaceable unit and the cartridge are separated, and to activate the current source it is required to insert mechanically the cartridge into the non-replaceable unit. The mechanical removal of the cartridge from the non-replaceable unit results also in removal of the consumable materials and the by-products of the chemical reaction. |
