Electrolysis of hydrogen sulfide in aqueous solutions has been investigated as a possible route for the low cost production of hydrogen and sulfur. Studies carried out at 85 Cel in an H2S saturated 1 M NaOH solution (pH = 8) indicate that electrolysis could be conducted for several hours at 0.5 to 0.6 V and at current densities of 100 mA cm2. Hydrogen evolution has been identified at the cathode and sulfur production at the anode, both at high Faradaic efficiencies, during the initial stages of electrolysis in single-compartment electrolytic cells. Polysulfides are also formed during electrolysis, which are highly soluble in alkaline solutions. The effect of sulfides and polysulfides on the continued production of hydrogen and sulfur, as well as the use of separating membranes between anolyte and catholyte, are being investigated.
