Fuel cell vehicle (FCV) is different from traditional vehicle in structure, more attention should be paid on its crash safety. In this paper, the structural features of FCV are emphatically studied. A finite element model for the frontal crash of the FCV is created, and the design scheme of vehicle safety performance is determined through numerical simulation with LS-DYNA. In addition, based on the features of FCV, some thoughts on its crash test method are expounded. The frontal crash test on a real vehicle verifies the effectiveness of the modification de-sign of vehicle structures.
