Electrochemical oxygen production method using solid electrolyte is introduced. By using oxygen pumping with oxide ion conductor, pure oxygen can be easily obtained. In particular, steam electrolysis and high temperature CO_2 reduction are highly interesting for energy efficient oxygen production by using heat energy. For both technologies, oxide ion conductor with high chemical stability is essentially requested. The current status of the oxide ion condor is reviewed. In particular, perovskite oxide of LaGaO_3 is highly expecting for intermediate temperature steam and CO_2 electrolyzer. On the other hand, simple oxygen pump is also interesting technology to get pure oxygen in spite of simple structure. Although electricity is required, electrochemical oxygen production method is one of the promising method to obtain the pure oxygen with simple device.
