    摘要： An electrochemical cell system is configured to utilize an oxidant reduction electrode module containing an oxidant reduction electrode mounted. The oxidant reduction electrode module is configured for coupling to a cell cover and immersion into an ionically conductive medium of an electrochemical cell, the oxidant reduction electrode module comprising a housing configured to define a gaseous oxidant receiving space therein; an oxidant reduction electrode having an oxidant facing side and an ionically conductive medium facing side, the oxidant reduction electrode mounted to said housing such that the oxidant reduction electrode defines a boundary wall for the gaseous oxidant receiving space, with the oxidant facing side facing inwardly to the gaseous oxidant receiving space and the ionically conductive medium facing side facing outwardly for exposure to the ionically conductive medium; and a gaseous oxidant inlet and a gaseous oxidant outlet in communication with the gaseous oxidant receiving space; and wherein the gaseous oxidant inlet is configured to allow an oxidant into the gaseous oxidant receiving space, the oxidant reduction electrode is configured to absorb the gaseous oxidant via the oxidant facing side and reduce the gaseous oxidant during discharge of the electrochemical cell.

    摘要： 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.

    摘要： The present disclosure relates to an electrochemical cell comprising a fuel electrode for oxidizing a fuel, an oxidant electrode for reducing an oxidant, and an ionically conductive medium for conducting ions between the fuel and oxidant electrodes to support electrochemical reactions at the fuel and oxidant electrodes. The ionically conductive medium comprises at least one active additive for enhancing (controlling the rate, overpotential and/or the reaction sites for) at least one electrochemical reaction within the cell. The cell further comprises an additive medium in contact with the ionically conductive medium and containing the at least one active additive capable of corroding or dissolving in the ionically conductive medium. The additive medium and/or casing is configured to release the active additive to the ionically conductive medium as a concentration of the active additive in the ionically conductive medium is depleted during operation of the cell.
