OXYGEN REDUCTION APPARATUS AND REFRIGERATOR

摘要

PROBLEM TO BE SOLVED: To provide an oxygen reduction apparatus that is made not to generate hydrogen, in an oxygen reduction apparatus utilizing a solid polymer electrolyte membrane.SOLUTION: Provided is an oxygen reduction apparatus 200 utilizing a solid polymer electrolyte membrane process and in which a voltage is applied while maintaining a constant-current control until the potential difference between an anode 208 and a cathode 210 reaches an upper limit potential difference and upon reaching the upper limit potential difference a constant voltage control is carried out so as not to exceed the upper limit potential difference.
