Patent number: 7550072Abstract: A nitric acid solution containing ions of any one element selected from the group consisting of rare element FP of Ru, Rh and Pd and a rare element of Re is electrolytically reduced by electrolyzing at a constant current to thereby deposit the ions of the element on an electrode. Alternatively, a nitric acid solution containing ions of two or more elements selected from the group consisting of rare element FP of Ru, Rh and Pd and a rare element of Re is electrolytically reduced by electrolyzing at a constant current to thereby collectively deposit the ions of the elements on an electrode. Alkaline water is electrolyzed by using the thus obtained electrodeposit electrode directly as it is as a catalytic electrode to efficiently generate hydrogen. Thus, a clean and sustaining energy system integrating the nuclear energy with the fuel cell power generation is provided.Type: GrantFiled: August 4, 2004Date of Patent: June 23, 2009Assignee: Japan Nuclear Cycle Development InstituteInventors: Masaki Ozawa, Tetsuo Ikegami
