ABSTRACT:
An oxygen concentration regulator for regulating the oxygen concentration in gases comprises an oxygen ion conductive solid electrolyte body, at least two separate electrodes contacting the solid electrolyte body so as to form an electrolysis cell, said cell having complex impedance characteristics which when graphed exhibit a curve similar to that shown in FIG. 3 hereof, AC power supplying means for applying an AC electric voltage across said electrolysis cell, said AC power supplying means being operable only at an AC frequency which is not lower than a frequency whose complex impedance characteristics, when graphed in the manner shown in FIG. 3 hereof, correspond to point B of said graphed complex impedance characteristic curve, and means for affirmatively applying a DC current across said electrodes, said DC current regulating the oxygen concentration in gases.
The present invention is to provide an oxygen concentration regulator which can easily and efficiently control an oxygen partial pressure on at least one electrode side with a less power consumption and a simple structure.
