Biogalvanic metal-oxygen cell
Abstract
Abstract A biogalvanic metal-oxygen cell encased in an oxygenpermeable silicone rubber membrane having one metal anode, two oxygen cathodes disposed on both sides of said anode comprising silver screens to which a catalytically active material is applied, and electrolyte chambers between the anode and the cathodes. The edge of the metal anode is joined to a plastic frame of greater width than the metal anode for the formation of the electrolyte chambers. The marginal areas of the silver screens of the cathodes are free of catalytically active material and are extended across the plastic frame and joined to each other. The silicone rubber membrane encases the cathodes and the marginal areas of the silver screens so as to make close contact, and a silicone rubber jacket is applied over the portion of the silicone rubber membrane which encases the marginal areas of the silver screens.
