Recently, the fuel cell vehicles (FCV) are actively developed in the world. JARI has been done and examined the basic data for FCV standardization as the entrustment of NEDO (New Energy and Industrial Technology Development Organization) from 2000. The safety evaluation methods of fuel leakage at the normal usage condition and the collision condition were examined, so that FCV use the compressed hydrogen gas as the fuel source. The crash test was performed using the moving barrier as simulated FCV to examine the fuel leakage measuring method, as one of the safety evaluation methods of FCV. The fuel leakage detection was examined using the flow meter measurement method, as one of the fuel leakage measurement methods. The result showed that the sample fuel cell stack is not scattered, and that in the measurement with the flow meter, the gas leakage was undetectable. For the covering abstract see ITRD E825082.
