Combined system of fuel cell and air-conditioning apparatus

A combined system of a power generator and an air-conditioning apparatus, said combined system comprising:

• a metal hydrides storage tank having a hydrogen-storage alloy accommodated therein;
• a power generator for generating a power with hydrogen as a fuel;
• an air-conditioning apparatus for cooling air with a cooling power generated in desorbing hydrogen from said metal hydrides storage tank;
• and
• hydrogen compressor means for sucking hydrogen out of said total hydrides storage tank to generate said cooling power required for said air-conditioning apparatus and pressure-feeding said hydrogen into said power generator.

A combined system of a power generator and an air-conditioning apparatus, said combined system comprising:

• a plurality of metal hydrides storage tanks respectively having hydrogen-storage alloys accommodated therein;
• a power generator for generating a power with hydrogen as a fuel;
• hydrogen compressor means for sucking hydrogen out of at least one metal hydrides storage tank among said plurality of metal hydrides storage tanks and pressure-feeding said hydrogen into another metal hydrides storage tank different from said metal hydrides storage tank;
• hydrogen supply means for supplying said hydrogen pressure-fed by said hydrogen compressor means into said power generator according to a load of said power generator;
• and
• an air-conditioning apparatus for cooling air with a cooling power generated in said desorbing hydrogen from said metal hydrides storage tank and heating air with a heat generated in absorbing hydrogen into said another metal hydrides storage tank.

A combined system of a power generator and an air-conditioning apparatus, said combined system comprising:

• a metal hydrides storage tank having a hydrogen-storage alloy accommodated therein;
• a power generator for generating a power with hydrogen as a fuel;
• hydrogen compressor means for sucking hydrogen out of said metal hydrides storage tank in response to a load of said power generator and pressure-feeding said hydrogen into said power generator;
• and
• an air-conditioning apparatus having cooling power generator means for converting said power generated by said power generator to a cooling power, said air-conditioning apparatus being driven with said cooling power generated by said cooling power generator means end a cooling power generated in desorbing said hydrogen from said metal hydrides storage tank.
