초록
The use of new and renewable energy is essential to solve the problem of increasing fossil fuel use due toindustrial development. The paradigm of the automobile industry has changed due to the strengthening ofenvironmental regulations in developed countries, and the development of eco-friendly cars is underway. Fuel cellelectric vehicles (FCEVs), which use hydrogen as fuel, require strict standards for fuel-related components. Inparticular, check valves for FCEV control high-pressure hydrogen and thus, must be sufficiently strong for thechallenging environment caused by high-pressure hydrogen. Therefore, this study used DEFORM 3D, a regularfinite element analysis program, to check the moldability of check valves for FCEV, design the process, verifyreliability through single streamline analysis, tensile tests, and ANSYS simulations, and identify suitable materialsfor the high-pressure hydrogen environment.
