<P>PROBLEM TO BE SOLVED: To provide a fuel reforming apparatus capable of continuing or stopping its running by detecting an abnormality of the fuel reforming apparatus without imposing a load on a fuel cell and the fuel reforming apparatus and performing a stable running, and a fuel cell power generation apparatus using the fuel reforming apparatus and its operation method. <P>SOLUTION: In an apparatus for supplying a reformed gas to an apparatus for utilizing hydrogen such as a fuel cell, which is equipped with a reformer for reforming a hydrocarbon fuel and a carbon monoxide transformer and/or a carbon monoxide remover for reducing the carbon monoxide concentration in the reformed gas, a hygrometer to measure the humidity of the reformed gas is installed at a position downstream from the carbon monoxide transformer or the carbon monoxide remover and upstream from the apparatus for utilizing hydrogen. When a dew point indicated on the hygrometer exceeds a threshold value specified in advance, it is judged that an abnormality occurs to the fuel reforming apparatus. When the abnormality occurs to the fuel reforming apparatus, the running of the fuel cell power generation apparatus is stopped or continued by reducing the load or increasing the amount of flowing water for reforming. <P>COPYRIGHT: (C)2007,JPO&INPIT |
