Abstract:
1. An electrochemical cell system comprising: one or more electrochemical cells, each comprising: a liquid ionically conductive medium for conducting ions between the fuel and oxidant electrodes to support electrochemical reactions at the fuel and oxidant electrodes; a housing configured to contain the ionically conductive medium in the one or more electrochemical cells; a gas permeable and liquid impermeable membrane positioned along a portion of the housing and configured to close the portion of the housing to contain the ionically conductive medium therein, the gas permeable and liquid impermeable membrane having an inner surface facing the ionically conductive medium wherein the inner surface comprises a first portion and a second portion; wherein the first portion of the gas permeable and liquid impermeable membrane does not have the oxidant electrode active material and provides a vent for the cell to permit gas in the housing to permeate therethrough for venting of the gas from the one or more electrochemical cells and the second portion of the gas permeable and liquid impermeable membrane has the oxidant electrode active material to comprise the oxidant electrode; and wherein the fuel electrode and the oxidant electrode are configured to, during discharge, oxidize the metal fuel at the fuel electrode and reduce an oxidant at the oxidant electrode to generate a discharge potential difference therebetween for application to a load.
