<P>PROBLEM TO BE SOLVED: To provide a technique capable of easily determining the deterioration of a device utilizing fuel, such as a fuel cell. <P>SOLUTION: A gas detection system detecting the prescribed gas present in the prescribed space includes: a gas concentration detection section for detecting the concentration of the specific gas; a recording section; a notice section; and a determination section which, when determining that the gas concentration detected by the gas concentration detection section is higher than a first threshold value, causes the notice section to notice the fact and, when determining that the gas concentration is higher than a second threshold value and lower than the first threshold value, does not cause the notice section to notice the fact but causes the recording section to record specific information. <P>COPYRIGHT: (C)2009,JPO&INPIT |
