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.

以CsH_2PO_4/SiP_2O_7复合电解质为电池，在200℃下进行了电化学抽氢研究。当加湿的一氧化碳进入阳极时，氢气在阴极的释放速率符合法拉第定律。在该体系中，极化过程中阳极的水煤气移位反应得到了电化学的促进。湿化一氧化碳的过电位比湿化氢气高得多。铜尖晶石催化剂位于阳极气体的上游，由于在催化剂上形成氢，在低电流密度下降低了阳极过电位。
