摘要：

This study is concerned with oxygen depolarized electrolysis of NaCl by the use of beta -alumina solid electrolyte and molten salts. In the electrolysis, dry chlorine gas and pure molten sodium hydroxide are produced from sodium chloride, oxygen and water. Because the oxygen reduction proceeds very smoothly in the molten sodium hydroxide, this process is very promising for the future. The theoretical decomposition voltage of this process is estimated to be 1. 5 V, which is lower than that of the process without an oxygen cathode by 1. 1 V. The model cell study shows that a terminal voltage of 3 V at 50 a dm** minus **2 is attainable.
