<P>PROBLEM TO BE SOLVED: To obtain a fuel cell power generation system capable of realizing a substitution function of reaction gas or an air mixing prevention function preventing air from mixing into a reaction unit, by enabling conservation gas to be stored in a conservation gas reservoir at a low-pressure state and doing away with pressurized manufacturing or a pressurized storage of conservation gas, and that, by appropriately selecting supply and exhaust operations of controlled fluid. <P>SOLUTION: The conservation gas reservoir 6 is so structured to have a movable barrier rib 7b zone an inside of a rigid outside vessel 7a into a first sub space 7c and a second sub space 7d. The barrier rib 7b is endowed with airtightness and elasticity, made to move by a pressure difference between the first sub space 7c and the second sub space 7d, and gives and takes mutual volumes of the first sub space 7c and the second sub space 7d. The first sub space 7c has nitrogen supplied from a nitrogen generator 5, stored at a low-pressure state larger than 1.0 and not larger than 1.1 atmospheric pressure. <P>COPYRIGHT: (C)2008,JPO&INPIT |
