Carbon Paper

Carbon paper is an important component of the fuel cell membrane electrode, located between the bipolar plates and the catalyst layer. It is a vital structure that supports the catalyst layer and collects current, while providing multiple channels for gas, protons, electrons, and water for electrode reactions. The choice of gas diffusion layer during stack design has a significant impact on fuel cell performance and lifespan.

Detailed Introduction


► From the beginning of cutting carbon fibers to the application of the microporous layer, the entire process chain is developed, produced, and sold in one line

► In the process of preparing the carbon paper raw paper, domestic carbon fiber raw materials are used, and the pore size, air permeability, and thickness are easily controlled by controlling the surface density and length of the carbon fibers;

► Breakthrough in core technology

Highly uniform dispersed carbon fiber paper technology (uniformity issue)

Continuous carbonization and graphitization with thermally coupled technology (cost issue)

Three-dimensional cross-linking technology of highly conductive nanocarbon materials and carbon fibers (performance issue)
