OXYGEN PUMP

摘要

PROBLEM TO BE SOLVED: To provide an oxygen pump improved in the joining strength between an electrode film and a lead member. SOLUTION: The area of a bonded part by a sintered compact 8 is enlarged by making the area of the anode electrode film 3 smaller than the area of the cathode electrode area 2. As a result, the adhesion strength is improved and therefore the thermal strain generated by heating and energizing is suppressed and the disconnection due to the thermal strain can be prevented.
