NOVELTY - A hydrogen generating apparatus (300) comprises a chamber (301) containing an aqueous solution and having an outlet to discharge hydrogen formed in one side of the chamber; and a membrane (302) formed inside the chamber adjacent to the outlet, for selectively permitting passage for the hydrogen. The apparatus further comprises a membrane brace (306) interposed between the aqueous solution and the membrane so as to support the membrane; and an adhesion layer (308) interposed between the membrane brace and the membrane, for securing the membrane.    USE - As a hydrogen generating apparatus for generating hydrogen in a fuel cell power generation system for converting chemical energy of the hydrogen into electrical energy (claimed); useful in portable electronic devices.    ADVANTAGE - In hydrogen generating apparatus, overflowing of the reagents in the hydrogen generating reaction can be prevented, for higher efficiency in the fuel cell. With the improvement in efficiency of the fuel cell power generation system, the volume of the system can be reduced, allowing for easier application to mobile devices. The system efficiency can be increased by way of a simple process using a polytetrafluoroethylene (PTFE) film. The fuel efficiency can be improved, as pure hydrogen gas can be supplied to the fuel cell after a twofold filtering by the membrane brace and the membrane.    DETAILED DESCRIPTION - A hydrogen generating apparatus (300) for generating hydrogen, comprises a chamber (301) containing an aqueous solution and having an outlet to discharge the hydrogen formed in one side of the chamber; and a membrane (302) formed inside the chamber adjacent to the outlet, for selectively permitting passage for the hydrogen. The apparatus generates hydrogen through a dissociation reaction of an aqueous solution using electrons obtained by an ionization of a metal. The hydrogen generating apparatus further comprises a membrane brace (306) interposed between the aqueous solution and the membrane so as to support the membrane; and an adhesion layer (308) interposed between the membrane brace and the membrane, for securing the membrane. The membrane brace permits passage for the hydrogen and prevents passage for the aqueous solution. An INDEPENDENT CLAIM is included for a fuel cell power generation system comprising a hydrogen generating apparatus; and a fuel cell configured to produce an electrical current by receiving the hydrogen generated by the hydrogen generating apparatus and converting chemical energy of the hydrogen into electrical energy.
