To address the safety concerns of Proton Exchange Membrane Fuel Cell Electric Vehicles (PEMFCEV), this paper uses the fault tree method to explore the factors affecting the safety of PEMFCEV, analyzes the potential safety hazards of proton exchange membrane fuel cell systems, power batteries and high-voltage electrical circuits, and elaborates the current domestic and foreign PEMFCEV manufacturers’ safety prevention and control strategies adopted for hydrogen leakage, power battery, and electrical safety. The results show that the current safety measures for PEMFCEV can prevent and control foreseeable safety risks.
