At present, under the circumstance that the large-scale development of fuel cell commercial vehicles and the cost reduction path of hydrogen have been established, and the expected reduction in fuel cell costs remains unchanged, the future of fuel cell commercial vehicles is promising. In the global carbon neutralization trend, the deep decarbonization in the transportation field becomes critical. Fuel cell vehicles are the development trend of global power electrification, and are "non-carbon" in heavy trucks, ships, aircraft and other scenarios.
