ABSTRACT:
In the invention, an electrochemical cell including an oxygen reducing cathode, an oxygen generating anode and an electrolyte, and having both a deoxygenating function and an oxygen generating function is coupled to a chamber in such a manner that, when the oxygen concentration in the chamber is much higher than a predetermined value, the deoxygenating function is utilized to decrease the oxygen concentration and when the oxygen concentration in the chamber is much lower than the predetermined value, the oxygen generating function is utilized to increase the oxygen concentration so that the oxygen concentration in the chamber is maintained at the predetermined value.
