<P>PROBLEM TO BE SOLVED: To eliminate requirement of an exclusive hydrogen concentration detector in order to measure a concentration of hydrogen contained in a gas generated from a cooling liquid in a cooling device of a fuel cell for a vehicle. <P>SOLUTION: A reserve tank for storing a part of the cooling liquid flowing-in from a fuel cell to a radiator is provided, and a pump connected to a gas area where the gas at an upper part of the reserve tank is stayed and pressurizing the inside of the gas area is provided. A hydrogen detector for detecting the concentration of hydrogen in a front room is provided, and a gas passage having one end connected to the gas area of the reserve tank and the other end extending to a portion near the hydrogen detector is provided. The gas passage is arranged such that the vehicle mounting state becomes high as it advances from a connection part of the gas area of the reserve tank toward the hydrogen detector. <P>COPYRIGHT: (C)2010,JPO&INPIT |
