| Outline of Final Research Achievements |
Energy reduction in water electrolysis was investigated. In usual, counter reaction of hydrogen evolution is oxygen evolution but instead of such large over potential reaction, we utilized anode reaction of I-. As the result, we succeeded to decrease cell voltage with about 1 voltage. Reaction product of I3- can be recycled by the reduction of SO32-. SO32- can be obtained easily by dissolving SO2 gas in water, where SO2 is reaction product in nonferrous metallurgical processing. We wish further development of this idea.
