<P>PROBLEM TO BE SOLVED: To provide a fuel cell system and a fuel-cell car reducing energy loss for smooth start at low temperatures, while being excellent in responsiveness to load changes. <P>SOLUTION: A warmup jacket 65 for hydrogen pump covers a hydrogen pump 60 requiring warmup operation and warms up the hydrogen pump 60. The warmup jacket 65 has a hydrogen storage material built in to generate heat by storing hydrogen and to absorb heat upon releasing the hydrogen. For warmup operation, hydrogen is introduced to heat the hydrogen storage material, with the generated heat transferred to the hydrogen pump 60. After the warmup operation, the heat generated in the hydrogen pump 60 is transferred to the warmup jacket 60 to heat the built-in hydrogen storage material to release the hydrogen for regenerating operation. <P>COPYRIGHT: (C)2004,JPO |
