<P>PROBLEM TO BE SOLVED: To provide a gas supply device capable of easily and smoothly adjusting dew points of gas supplied, to provide a fuel cell evaluation testing device, and to provide a fuel cell system. <P>SOLUTION: The gas supply device 10 is capable of supplying a fuel cell 30 with mixture gas prepared at a given dew-point temperature T<SB>d</SB>by mixing low-humidity gas flowing in a low-humidity flow channel 33 and high-humidity gas flowing in a high-humidity flow channel 35. A mixture ratio r of the low-humidity gas to the high-humidity gas is set at a value found by substituting a supply pressure P of the mixture gas supplied to the fuel cell 30, a saturated vapor pressure P<SB>DP</SB>corresponding to supply target dew points of the mixture gas, and a saturated vapor pressure P<SB>B</SB>of the high-humidity gas into formula 1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
