To provide an oxygen pump which is capable of conducting the efficient movement to uniformly heat an oxygen pump element and to reduce its thermal loss by forming a resistance heater or infrared reflection layer on a heat-resistant substrate.
The oxygen pump is composed of an oxygen pump element 6 having positive and negative electrode membranes 5a and 5b formed on both sides of an oxygen ion conducting substrate 4, heating means 10a and 10b having the resistance heaters 12a and 12b, to which the infrared radiation layers 16a and 16b are laminated, are formed on the heat-resistant substrates 11a and 11b, a conducting means 8 which is electrically connected with the electrode membranes 5a and 5b and a gas permeable insulation materials 9a and 9b which electrically insulate the oxygen pump element 6 and the heating means 10a and 10b. The oxygen pump can heat the resistance heaters 12a and 12b to which the infrared radiation layers 16a and 16b are laminated and the oxygen pump element 6 uniformly and high efficiently by arranging the negative electrode membrane of the oxygen pump element 6 and the resistance heaters 12a and 12b of the heating means 10a and 10b to a relative structure.
