A process for improved performance in at least one fuel cell, having a loss in power output of at least 5% of an initial power output, wherein the fuel cell comprises a cathode, an anode, an anode chamber, a cathode chamber, a fuel comprising an anolyte that flows through the cell, and a catholyte gas, wherein the fuel cell is connected to an external load, and wherein the process includes the steps of taking the load off the fuel cell; and applying an external electric field from an external power source to the fuel cell to reverse electrochemical reactions until at least 5% of the lost power output is regained. Purging the fuel cell further enhances regeneration of the cell.

Method for regeneration of performance in a fuel cell

The present invention relates to an electrochemical cell and a process for converting anhydrous hydrogen halide to halogen gas using a membrane-electrode assembly (MEA) or a separate membrane and electrode arrangement, such as gas diffusion electrodes with a membrane.
