<P>PROBLEM TO BE SOLVED: To provide a hydrogen fuel feeding system which is equipped with a plurality of reactors and suppresses variation of hydrogen feed rate associated with changeover from a regenerating step to a reforming step in one reactor. <P>SOLUTION: The hydrogen fuel feeding system 12 is equipped with a pair of reactors 18, wherein each reactor 18 allows a reforming step of producing hydrogen-containing fuel gas from fed raw material and a regenerating step of increasing the temperature lowered by the reforming step to a temperature capable of reforming by burning fed gas for regeneration. A control device selects opening or closing of each valve of a changeover device 20, so that fuel gas is continuously fed to a fuel cell 14 by alternately carrying out the reforming step and the regenerating step in each reactor 18 without carrying out the reforming steps in the reactors 18 at the same time, and the control device changes one reactor 18 from the regenerating step to the reforming step while the other reactor 18A is in the reforming step, so that preparation for feed of fuel gas to the fuel cell 14 is made. <P>COPYRIGHT: (C)2007,JPO&INPIT |
