Abstract
An oxygen recovery system configured to recover evolved oxygen from a regenerative electrochemical cell. The electrochemical cell includes an oxygen reduction cathode, a fuel electrode configured to be a fuel anode when the cell is operated to generate electricity and a cathode for reducing fuel thereon when the cell is operated to regenerate the fuel, and an oxygen evolution anode that is configured to evolve oxygen from an electrolyte solution when the cell is operated to regenerate the fuel. The oxygen recovery system includes an oxygen separator located downstream of the oxygen evolution anode in a recharge direction of flow. The oxygen separator is configured to separate the evolved oxygen from the electrolyte solution. An oxygen recovery path is disposed between the oxygen separator and the oxygen reduction cathode. The oxygen recovery path is configured to direct the evolved oxygen separated from the electrolyte solution to the oxygen reduction cathode.
