The feasibility of using anodic depolarization for water electrolysis in a system containing a solid polymer electrolyte is examined. Anodic depolarization in electrolysis helps reduce energy consumption by a half. Sulfur dioxide (sulfurous anhydride) and some organic compounds, methanol in particular, can be used as depolarizers.
