What impact does carbon fiber have in the field of hydrogen energy?
As the global demand for clean energy continues to increase, hydrogen energy, as an ideal alternative energy source, has become increasingly important. In the storage and transportation of hydrogen energy, hydrogen storage technology has become a key link. Carbon fiber has become an important material for improving hydrogen storage efficiency and safety due to its light weight, high strength and corrosion resistance. At the same time, as the core application technology of hydrogen energy, the performance improvement of hydrogen fuel cells is also inseparable from the support of carbon fiber.

Lightweight carbon fiber for hydrogen storage bottles has become a key material for high-pressure hydrogen storage bottles due to its high strength and low density. Through wet or dry winding processes, carbon fiber can significantly reduce the weight of hydrogen storage bottles while improving their pressure resistance. For example, the type III hydrogen storage bottle uses a metal liner and carbon fiber winding, while the type IV hydrogen storage bottle uses a plastic liner and all-carbon fiber winding, which further optimizes the hydrogen storage efficiency. This lightweight design not only improves the hydrogen storage density, but also reduces transportation energy consumption, making it an ideal choice for hydrogen fuel cell vehicles and hydrogen power stations.

Core components of hydrogen fuel cells In hydrogen fuel cells, carbon fiber is used as the substrate of the gas diffusion layer, which has the characteristics of high porosity and high conductivity. The function of the gas diffusion layer is to transmit gas, drain water and conduct electricity, and its performance directly affects the efficiency of the fuel cell.
