| Research Abstract |
Electrochemical hydrogen pumping was investigated with a cell consisting of CsH_2PO_4/SiP_2O_7 composite electrolyte at 200℃. When humidified carbon monoxide was fed to the anode, the evolution rate of hydrogen at the cathode obeyed the Faraday's law. In this system, the water gas shift reaction was promoted electrochemically at the anode during polarization. The overpotential was much higher in humidified carbon monoxide than in humidified hydrogen. The Cu spinel catalyst located upstream of anode gas reduced anodic overpotential at low current densities due to the formation of hydrogen over the catalyst.
