NOVELTY - A fuel-cell electric-power generation system hydrogen generator which is chemical reaction tank (1) containing a catalyst and into which an alkaline electrolyte solution is poured. The electrolytic cell (2) consists of division (I) with a cathode and to which pure water is supplied, division (III) with an anode and to which pure water is supplied, and division (II) into which electrolyte solution is poured. When the alkaline electrolyte solution is decomposed in tank (1), hydrogen gas is generated. Hydrogen gas is supplied to the fuel-cell module (3).    USE - Fuel-cell electric-power generation system.    ADVANTAGE - The fuel-cell electric-power generation system has easy and economical maintenance property, does not use high-pressure hydrogen or lead battery, and has an auxiliary power supply with quick charge-discharge characteristics.    DETAILED DESCRIPTION - A fuel-cell electric-power generation system has a secondary battery module (A), a hydrogen generator, an electrolysis system, and an auxiliary power supply (5) for fuel-cell module. The hydrogen generator is chemical reaction tank (1) containing a catalyst and into which an alkaline electrolyte solution is poured. The electrolytic cell (2) consists of division (I) equipped with a cathode and to which pure water is supplied, division (III) equipped with an anode and to which pure water is supplied, and division (II) into which alkaline electrolyte solution is poured. Division (II) contacts divisions (I,III) through ion-exchange membranes (I,II), respectively. Piping (I) is provided for flowing alkaline electrolyte solution generated in division (I) to tank (1). Piping (II) is provided for pouring pure water decomposed by the catalyst to divisions (I,III) through a pump, when alkaline electrolyte solution flows into tank (1). When the alkaline electrolyte solution is decomposed in tank (1), hydrogen gas is generated. Hydrogen gas generated in tanks (1,2) is supplied to a fuel-cell module (3), with reduced discharge of toxic substances, such as carbon dioxide and nitrogen oxide.
