The safety of hydrogen release and discharge from a fuel cell vehicle was evaluated using CFD (Computational Fluid Dynamics) tests in various situations. First, the validity of the locations of the hydrogen sensors installed in Hyundai fuel cell vehicle and the workshop were tested. In addition, the discharge tests of the fuel cell vehicle based on SAE J2578 were conducted in non-ventilated, ventilated and outdoor modes. Through these tests, it was verified that the hydrogen sensor locations are suitable for the detection of hydrogen leakage and SAE J2578 regulation is satisfied in the fuel cell vehicle.
