<P>PROBLEM TO BE SOLVED: To provide a pressure sensor capable of shortening the start time of a fuel cell system as a result, by thawing moisture in a short time. <P>SOLUTION: In the fuel cell system, a hydrogen pressure sensor 16 wherein a pressure inlet port 59 is formed, an air pressure sensor 24, and the bottom of a pure water pressure sensor 30 are so constituted that they do not become larger than the outside diameter of the clamping face of a pressure sensor mounting boss 71. Thereby, in the fuel cell system, since the heat generated from a pressure sensor thawing heaters 17, 25, 31 is transmitted efficiently to the hydrogen pressure sensor 16, the air pressure sensor 24, or the pure water pressure sensor 30, the moisture in the hydrogen pressure sensor 16, the air pressure sensor 24, or the pure water pressure sensor 30 can be thawed in a small amount of time, which can ensure the shortening of the start time of the system as a whole. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
