<P>PROBLEM TO BE SOLVED: To solve such problems that in a current humidifying system used in a fuel cell system, since the humidification of gas is necessary when gas is supplied to a fuel cell after scavenging, a tank or the like for ensuring water is made necessary, and when the tank is installed, water stored in the tank is possibly freezed, a heat source (a heater for example) for thawing is made necessary, and starting of the fuel cell system in starting at a freezing point requires much more time. <P>SOLUTION: A humidifying system is equipped with a fuel cell 1, a fuel cell system having the fuel cell, a humidifying device 20 for humidifying gas to be supplied to the fuel cell 1 and gas exhausted from the fuel cell through a hollow fiber membrane 21, and supply piping 12 supplying the specified amount of pure water from the fuel cell system to the humidifying device when a freezing judging means 20 judging whether water in the fuel cell system freezes or not judged that the water freezes. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
