<P>PROBLEM TO BE SOLVED: To provide a hydrogen fuel-supplying system capable of supplying the fuel gas which is obtained by a reforming reaction and contains hydrogen to a fuel cell while corresponding to load change, and also to provide a fuel cell system which is provided with the above hydrogen fuel-supplying system and follows the output variation of a fuel cell as a whole. <P>SOLUTION: In a reactor composing the hydrogen fuel-supplying system, a reforming process and a regeneration process are alternately performed. The reforming process comprises generating a hydrogen-containing fuel gas by reforming a supplied raw material, and the regeneration process comprises performing the catalytic combustion of a gas mixture prepared by mixing a supplied air for combustion and a gas for regeneration in a mixing space 84 to elevate the temperature lowered in the reforming process to a reformable level. The fuel gas generated in the reforming process is consumed in the fuel cell. When the reduction of hydrogen consumption is required during the operation of the reforming process accompanied by load degradation of the fuel cell, the supply amount of a reforming raw material is lowered, and a flow-keeping gas for keeping the flow of in-system gas of the reactor and fuel cell is introduced to quickly change to the state according to raw material prorogation. <P>COPYRIGHT: (C)2007,JPO&INPIT |
