Abstract

In order to improve the efficiency of electrolysis in the hybrid sulfur cycle for hydrogen production, the feasibility of molten salt electrolysis for the electrochemical step has been investigated. The process designed and examined in this paper is concerned with SO2 electrooxidation in the hydrogen sulfate melts, which is related to the SO2 depolarized process developed by Westinghouse Electric Corporation. Using a porous carbon anode, the electrolysis was performed at the cell voltage of 1.2 V at 100 A·m-2. It is expected that the efficiency of the electrolysis will be improved by modification of gas (SO2 and H2O) supplying method.
