2. Large size and width
3. Extremely low surface roughness

Advantages:

1. Increase the contact area between the gas diffusion layer and the membrane electrode to reduce the contact resistance.
2. Reduce surface spikes, prevent puncturing of membrane electrodes, and improve the lifespan of membrane electrodes.
3. Excellent water and gas transmission performance.

Application:

AEM nickel powder felt diffusion layer is used to promote the electrochemical reaction of gas. The conductive layer is a layer connecting the catalyst layer and the electrode substrate. It has good conductivity and can effectively transfer electrons to the electrode substrate. The nickel powder felt gas diffusion layer plays the role of transferring gas and liquid, and has good gas diffusion performance and liquid permeability. The nickel powder felt gas diffusion electrode is characterized by a large surface area and high catalytic activity. Due to the presence of the catalyst, the gas diffusion electrode can realize the electrochemical reaction of the gas at a lower temperature and pressure, and improve the efficiency and rate of the reaction. In addition, the nickel powder felt gas diffusion electrode also has good stability and corrosion resistance, and can operate stably for a long time in a complex environment.
