<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of being humidified even at extremely low temperatures without freezing. <P>SOLUTION: In this fuel cell system, a gas supplied to a fuel cell stack 14 is humidified by pure water. The fuel cell system is provided with: a film module 22 equipped with a pervaporation film 22c for selectively filtering and separating pure water from a nonfreezing solution in a decompressed atmosphere; a nonfreezing solution supply system 21 for supplying the nonfreezing solution to the film module 22; and humidification means 26, 13 and 31 for mixing, in the supply gas supplied to the cell stack 14, the pure water filtered by applying the decompressed atmosphere to the film module 22. The supply gas is humidified by using the pure water separated and extracted from the nonfreezing solution by the film module 22. <P>COPYRIGHT: (C)2004,JPO |
