Abstract
An electrochemical cell system is configured to utilize an oxidant reduction electrode module containing an oxidant reduction electrode mounted to a housing to form a gaseous oxidant space therein that is immersed into the ionically conductive medium. A fuel electrode is spaced from the oxidant reduction electrode, such that the ionically conductive medium may conduct ions between the fuel and oxidant reduction electrodes to support electrochemical reactions at the fuel and oxidant reduction electrodes. A gaseous oxidant channel extending through the gaseous oxidant space provides a supply of oxidant to the oxidant reduction electrode, such that the fuel electrode and the oxidant reduction electrode are configured to, during discharge, oxidize the metal fuel at the fuel electrode and reduce the oxidant at the oxidant reduction electrode, to generate a discharge potential difference therebetween for application to a load.
