Abstract

An electrochemical cell includes a fuel electrode configured to operate as an anode to oxidize a fuel when connected to a load. The cell also includes an oxidant electrode configured to operate as a cathode to reduce oxygen when connected to the load. The fuel electrode comprises a plurality of scaffolded electrode bodies. The present invention relates to an electrochemical cell system and method of resetting the electrochemical cell by applying a charge (i.e. voltage or current) to the cell to drive oxidation of the fuel, wherein the fuel electrode operates as an anode, and the second cell operates as a cathode, removing uneven distributions of fuel that may cause premature shorting of the electrode bodies to improve capacity, energy stored, and cell efficiency.
