1. Flexible and bendable
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.
