Abstract: With the introduction of energy conservation and environmental protection laws and regulations in major automobile producing countries and regions around the world, the R & D for various newtype power batteries is becoming more and more active, and hydrogen fuel cells are one of them. The widespread use of hydrogen fuel cells in new energy vehicles, electric trains, and aerospace is a complex system engineering that requires a series of technical challenges to overcome. The paper mainly introduces the latest developments in the hydrogen fuel cell industry chain and its related high-tech fibers, future market opportunities and challenges.

Key words: hydrogen fuel cell; high-tech fiber; aerospace; new energy vehicles; electric train
