NOVELTY - An electric power generation and hydrogen production apparatus consists of a water-electrolysis hydrogen generator (10) and a fuel cell (12). The hydrogen generator uses sulfur dioxide gas, and the fuel cell uses hydrogen. Hydrogen and sulfuric acid are generated in the hydrogen generator by electrolysis of aqueous sulfurous acid. Water and electric power are generated in the fuel cell using the generated hydrogen. Both are combined so that electric power generated in the fuel cell is used for electrolysis in the hydrogen generator.    USE - Electric power generation and hydrogen production apparatus is used in high grounds and islands.    ADVANTAGE - The electric power generation and hydrogen production apparatus enables utilization of sulfur dioxide gas generated from iron mills, volcanoes, etc. as fuel for electric power generation and hydrogen production, and generation of electric power supply even in areas where electric power generation is difficult. When water from a water tank is supplied to the cathode side of hydrogen generator, impurities generated by electrolysis can be washed and dissolved. Hence, reduction in electrolysis performance by accumulation of impurity at the cathode side is prevented.    DETAILED DESCRIPTION - An electric power generation and hydrogen production apparatus consists of a water-electrolysis hydrogen generator and a fuel cell. The hydrogen generator uses sulfur dioxide gas, and the fuel cell uses hydrogen. Hydrogen and sulfuric acid are generated in the hydrogen generator by electrolysis of aqueous sulfurous acid. Water and electric power are generated in the fuel cell using the generated hydrogen. Both are combined so that electric power generated in the fuel cell is used for electrolysis in the hydrogen generator. Excess hydrogen and/or electric power are taken out.
