<P>PROBLEM TO BE SOLVED: To provide a dehydrogenation catalyst capable of enhancing the reaction efficiency of a dehydrogenation reaction and a hydrogen supply device using the same. <P>SOLUTION: In the dehydrogenation catalyst which consists of a metal catalyst carried by a catalyst carrier made of a porous oxide film and takes out hydrogen by using a medium chemically repeating storage or supply of hydrogen, the water-absorption/film-thickness of the porous oxide film is set at 0.030-0.065 (mg/(cm<SP>2</SP>×μm)). Further, the hydrogen supply device is manufactured by using a dehydrogenation catalyst having a structure of 0.030-0.065 (mg/(cm<SP>2</SP>×μm)) of a water-absorption /film-thickness of porous oxide film, 1-4 nm of Pt catalyst size, 45-100 nm of micropore size, and 1-4 nm 1×10<SP>-6</SP>-1×10<SP>-5</SP>(m<SP>2</SP>/(s×μm)) of thermal-diffusivity/film-thickness of porous oxide film. <P>COPYRIGHT: (C)2008,JPO&INPIT |
