The project “Study on demonstration operation of multiple fuel cell vehicles in typical regions” carried out demonstration operation of fuel cell vehicles in four typical regions of Beijing，Tianjin and Hebei，Central Plains，Yangtze River Delta and Pearl River Delta，and conducted special tracking studies on more than 223 of them，to verify and analyze the safety，reliability and economy of fuel cell vehicles and their supporting infrastructure in actual operation. Through the formulation and implementation of the operation and maintenance system and emergency treatment plan of fuel cell vehicles and hydrogenation infrastructure，an operation team with operation and management experience was established，and the operation cost of fuel cell vehicles and hydrogenation station was tentative explored，laying a good foundation for demonstration operation in the next step.
