HIGH TEMPERATURE STEAM ELECTROLYTIC CELL

摘要

PURPOSE:To improve the airtightness of an electrolytic cell by adding SiO2 or MgO to oxide interconnectors which are used for joining unit electrolytic cells to each other in series while applying a pressure at a high temp. and joining the unit cells with the glass melt of the above oxide. CONSTITUTION:This high temp. steam electrolytic cell comprises the unit electrolytic cells and the oxide interconnectors 4 for joining the unit cells to each other in series. Each of the above unit electrolytic cells is provided with the cathode 3 on one surface of and the anode 2 on the other surface of the tubular oxygen ion conductive solid electrolyte 1. Further, SiO2 or MgO is added to the above interconnectors 4 and the unit electrolytic cells are joined with the glass melt of SiO2 or MgO and accordingly, the airtightness of the high temp. steam electrolytic cell can be improved.
