    摘要: A reforming apparatus for fuel cells capable of effectively removing carbon dioxide at a high temperature from a reformed gas which is produced by a steam reforming method, and of producing high-purity hydrogen gas with a high hydrogen conversion rate. A reforming apparatus for fuel cells includes a reformer for steam-reforming a raw material to produce hydrogen, and carbon dioxide removing apparatus for removing carbon dioxide gas by absorbing carbon dioxide from a reformed gas, which is produced by steam reforming in the reformer, using a material containing Ba2TiO4 as a main component as a carbon dioxide absorbent. The reforming apparatus for fuel cells may further include a second reformer for steam-reforming again the reformed gas from which carbon dioxide gas has been removed by the carbon dioxide gas removing means. Alternatively, the reformer for steam reforming may enclose the carbon dioxide removing apparatus which uses the carbon dioxide absorbent containing Ba2TiO4 as a main component so that carbon dioxide produced by steam reforming is removed by absorption within the reformer.
