PRIMARY ALUMINUM-AIR BATTERY ABSTRACT OF THE DISCLOSURE An aqueous electrolyte aluminum-air battery comprises one or more cells, each cell comprising a frame which defines an electrolyte chamber. The frame is made of a rigid material inactive to the electrolyte. The cell has a consumable aluminum anode and an air cathode spaced from the anode by said electrolyte chamber. Means are provided for admitting electrolyte solution into the electrolyte chamber. A vent exposes the electrolyte chamber to atmosphere. A hydrophobic membrane which is impermeable to the passage of electrolyte but permeable to the passage of hydrogen closes the vent. A surface of each cell anode is exposed to the flow of air. The amount of surface exposed is effective to dissipate heat generated at the anode.
