In recent years，the Chinese government has encouraged the application of fuel cell vehicles in long-distance，medium and heavy fields，and the demonstration operation of fuel cell heavy trucks in China has accelerated. From January to July in 2021，353 fuel cell heavy trucks were sold，mainly used in cold chain transportation，steel transportation，building materials transportation，muck transportation，etc. Typical fuel cell application scenarios include long-distance trunk transportation of general cargo，long-distance transportation of cold chain cargo，short reverse transportation，residue transportation and urban sanitation. At the same time，the number of fuel cell heavy card products is increasing，which can initially meet the requirements of demonstration application in various scenarios. In the long run，the application of fuel cell heavy truck has strong economic feasibility and technical feasibility，and has strong development potential. In the future，we should accelerate breakthroughs in key technologies of fuel cell heavy trucks，continuously improve economy，accelerate business model innovation，improve hydrogenation infrastructure and strengthen policy support，so as to accelerate the realization of economy and technological potential of fuel cell heavy trucks，and promote the continuous improvement of replacement rate of fuel cell heavy trucks in various typical application scenarios.
