What factors restrict the development of hydrogen fuel-powered battery vehicles in China?

The key factors restricting my country's hydrogen fuel cell vehicles At present, the bottlenecks restricting the development of hydrogen fuel cell vehicles in China include technical constraints such as fuel cell durability, key materials and core components, and hydrogen supply problems. 1) The durability of fuel power battery. Taking the basic requirements of vehicle fuel power batteries as an example, the operating life of the fuel power battery system for cars must reach 3000-5000h. The stable life of hydrogen fuel power batteries of related domestic companies is still around 3000h, while the international advanced technology can reach more than 5000h. 2) Weak key materials and core components. The foundation of key materials and components of fuel power batteries in my country is relatively weak. For example, the development of key materials such as fuel power battery electrocatalysts, proton exchange membranes, and carbon paper mostly stay in the laboratory and sample stage, and key components such as air compressors and hydrogen return pumps The lack of product supply has seriously affected the development process of my country's vehicle fuel power cell stack technology. 3) Hydrogen storage problem. The hydrogen storage density of the carbon fiber-wound metal-lined gas cylinder (Type Ⅲ) used in my country with a pressure of 35MPa is 3.9%, which can reach 5% by increasing the pressure to 70MPa; while the carbon fiber-wound plastic-lined gas cylinder (Type Ⅳ) is used for storage. The hydrogen density can be further increased to 5.5%. my country has not yet mastered the manufacturing technology for Type IV cylinders, and there are only research and development results for Type III cylinders of 70MPa, and no products. In addition, another path currently being explored and developed is organic liquid hydrogen storage, which is worthy of attention. There is a certain research foundation in China, but there is a lack of demonstration assessment. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
