<P>PROBLEM TO BE SOLVED: To provide a chemical heat-storage hydrogen-storage device capable of storing heat and hydrogen at the same time, and of leveling hydrogen consumption of a fuel cell. <P>SOLUTION: This chemical heat-storage hydrogen-storage device is provided with: a first reactor 17 where an endothermic reaction A for releasing hydrogen or an exothermic reaction A<SP>*</SP>of its reverse reaction for absorbing hydrogen is generated; a second reactor 18 where an exothermic reaction B for absorbing hydrogen below a predetermine temperature or an endothermic reaction B<SP>*</SP>of its reverse reaction for releasing hydrogen is generated in the same pressure condition as the pressure of the first reactor 17; a first communication tube 19 for making both the reactors communicate with each other; a first heat exchanger 20 for exchanging heat with the environment in the first reactor 17; a second heat exchanger 21 connected to a circulation circuit 14 for circulating a heat medium fluid between the fuel cell 11 and the second reactor 18 for heating the inside of the second reactor 18 for exchanging heat with the heat medium fluid heated by recovering exhaust heat of the cell 11 and for heating the heat medium fluid by recovering generated heat of the reaction B; and a second communication tube 22 for making a hydrogen supply tube 13 for supplying hydrogen to the cell 11 from a hydrogen supply device 12, and the communication tube 19 communicate with each other. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
