PROBLEM TO BE SOLVED: To prevent the progression of collapse of a catalyst disposed on the lower side, caused by a fallen catalyst from an opening of a partition member (supporting member) installed in a hydrogen generator.SOLUTION: A hydrogen generator includes a first supporting member 53 installed in a reactor vessel to support a catalyst, and a projection that is arranged on the periphery of an opening of the first supporting member and projects upward in the gravity direction. The supporting member has a supporting part opening larger than catalyst particles and the projection has a projection part opening larger than catalyst particles. The catalyst is thus suppressed from falling to prevent capacity degradation of the hydrogen generator caused by collapse of a catalyst below. |
