To positively deal with intermittent exhaust gas supply, and efficiently collect fuel constituent with less amount of a reaction object, by using an electrochemical reaction device for continuously performing oxidation reaction and reduction reaction.
For a process for collecting a hydrogen isotope that is a fuel constituent from the exhaust gas of a nuclear fusion furnace, for example, a solid electrolyte tube with oxygen ion permeability is provided, and an electrochemical reaction device 2 is used, where the electrochemical reaction device simultaneously performs oxidation reaction for supplying oxygen to a reaction object and reduction reaction for eliminating the oxygen from it. In this process, for example, when methane and vapor are supplied from an inlet 1, the mixture gas of hydrogen and carbon dioxide is discharged from the outlet of the electrochemical reaction device 2. The gas is sent to a palladium hydrogen permeation device 3 for separating into the hydrogen and non-permeation gas containing no hydrogen. When a reaction rate is insufficient, retreatment can be made. In that case, a tank for preventing mixture is used, thus improving collection efficiency.
