| Research Abstract |
Fuel cell vehicles and hydrogen stations will be commercialized in 2015. Metal fatigue is related to 80 % of failureaccidents. Hydrogen enters into metals and accelerates fatigue crack growth. In thisstudy, a carbon steel and stainless steel suppressed the acceleration of fatigue crack growth with the presence of hydrogen have been found. The carbon steel and stainless steel will contribute to ensuring the safety of FCVs and hydrogen stations.
