Abstract

In order to improve the electrolytic performance in the hybrid sulfur cycle for hydrogen production, the possibility of molten salt electrolysis for the electrochemical step in the process has been investigated. The process designed and examined in this paper is concerned with HBr electrolysis in LiBr-KBr melt at 400°C, which is related with so called "Mark 13" process. By using tile electrolyte composed of salt mixture and lithium aluminate powder matrix, the electrolysis could be performed at the cell voltage of 1.00 V in the case of 250 mA cm-2. The electrolysis performance may be improved by the addition of some electrocatalyst, for example Pt, to the carbon felt electrodes.
