Oxidant flow system for submerged metal air electrochemical cell

摘要

A system is provided for efficiently and conveniently circulating oxidant (e.g., air) across an air cathode of a sub-merged or partially submerged electrochemical cell. The electrochemical cell includes an air inlet in gaseous communication with a surface of the air cathode. A cathode frame is provided having designated passageways for causing air to flow in a multi directional path across the surface of the air cathode. The cathode frame provides access to an air outlet at a top end of the air cathode. Airflow has a gradient from the inlet to the outlet due to the increased temperature of the air imparted by heat of electrochemical reaction.
