Abstract: The demonstration application policy of fuel cell vehicles has promoted the rapid development of China's fuel cell vehicle industry, but at the same time, it has also put forward higher requirements for the safety application of fuel cell vehicles. Currently, safe operation of fuel cell vehicles in China still lack practical experience, and there is a lack of scientific and systematic theoretical guidance and top-level design in safety management and emergency support. In order to ensure the safe operation of fuel cell vehicles in China, starting with the analysis of potential risk points and safety guarantee mechanism of fuel cell vehicles, the PPRR crisis management model is used to conduct systematic analysis and research, combined with relevant national policy and standard requirements and local practical experience, and put forward relevant suggestions for improving the emergency management system from four aspects of crisis prevention, preparation, response and recovery. Based on the safety application requirements of fuel cell vehicles, this paper puts forward a comprehensive risk analysis and policy suggestions for the establishment of emergency management system, and provides a useful reference for relevant management departments to do a good job in safety management and emergency support.
