Abstract

A mechanically rechargeable air-metal source of current having one or more non-consumable gas diffusion positive electrode(s), one or more consumable negative metal electrode(s), an electrolyte based on water solutions of salts and/or bases and a housing enclosing the positive electrode(s) and the negative electrode(s), to create an inter-electrode gap, together with the electrolyte. The current source has a first unit, comprising a first body with the negative electrode(s), together with at least one first conduit for connecting to and distributing ambient air, at least one second conduit for distributing the electrolyte, and at least one third conduit for collecting reaction products in cooperation with the first conduit and the second conduit. Further, the current source has a second unit, comprising the negative metal electrode(s) and the electrolyte. The second unit is replaceably arranged in the housing, so that when the negative electrode(s) and the electrolyte are consumed, a fresh second unit can be inserted instead of the consumed second unit.
