Abstract
A metal/air battery is described having gas bubbled through the electrolyte. It includes: (a) a tank defining a reservoir for liquid electrolyte; (b) one or more metal-air cells disposed for immersion in electrolyte, each cell including at least one air cathode having a first surface disposed for contact with electrolyte and a second surface exposed to air and a metal anode disposed for immersion in electrolyte in facing spaced relation to the first cathode surface to constitute therewith an anode-cathode pair electrically coupled by electrolyte, (c) a bubbler tube extending horizontally in the electrolyte reservoir beneath each cell and serving to inject gas bubbles into electrolyte between the anode and cathode of each cell, and (d) means for providing a pulsating flow of gas to the bubbler tube(s).
