<P>PROBLEM TO BE SOLVED: To efficiently gasify liquid water and to make suitable injected amount of the liquid water. <P>SOLUTION: A gas humidifying apparatus humidifies gas supplied to a fuel cell composing a fuel cell system through a gas flowing path. The gas humidifying apparatus includes: a porous section which is arranged in the gas flowing path in a state of the gas passing inside and which gasifies the liquid water guided thereinside by heat obtained from the gas; a nozzle for injecting the liquid water toward the porous section; a measuring means for measuring a prescribed physical value in a position on the downstream side of the porous section in the gas flowing path; and a control means for controlling the injected amount of the liquid water from the nozzle based on the physical value measured by the measuring means. <P>COPYRIGHT: (C)2009,JPO&INPIT |
