A study was made on the method of controlling oxygen partial pressure in the range of 10<SUP>-4</SUP>10<SUP>-8</SUP> atm by the addition of oxygen into purified argon gas through stabilized zirconia cell. The oxygen partial pressures obtained by controlling the electric current passed through the cell and the feed rate of the carrier gas were found to agree well with theoretical values in the range of 10<SUP>-4</SUP> to 10<SUP>-6</SUP> atm oxygen partial pressure. Below 10<SUP>-6</SUP> atm, however, some discrepancy appeared between the theoretical and observed values, due to the oxygen partial pressure being reduced by the reaction with impurity gases such as hydrogen present in the argon. A discussion is also presented on the measured polarization curves for the anode and cathode of the stabilized zirconia cell.
