A prospective global market share of Electric vehicle (EV), Hybrid electric vehicle (HEV) and Hydrogen Fuel Cell Vehicle (HFCV) is expected to grow due to stringent emission regulation and oil depletion. However, it is essential to secure protection against high-pressure hydrogen gas and high- voltage in fuel cell vehicles and thus needs to develop a technique for safety assessment of HFCV. In this experiment 8 research institutes, including the Korea Automobile Testing and Research Institute, Hyundai Motor Company, took part in. This project was supported by the Ministry of Land, Transportation and Maritime Affairs of the Republic of Korea.
