Asymmetric Gradient Structure Flexible 1.8mm Titanium Felt Gas Diffusion Layer

The core material for AEM hydrogen production with completely independent intellectual property rights independently developed by Borsemai.
The main process of its preparation is:

Characteristic:

1. Both pore size and porosity can be controlled;
2. Gradient pore structure
3. Large specific surface area;
4. Excellent water and gas transmission performance

Specification parameters

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.

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.

PEM hydrogen production anode diffusion layer GDL

The anode diffusion layer is used for mass transfer of O2 and H2O in environments with high potential and acidity, requiring coatings with good corrosion resistance. The porous transport layer is located between the catalytic layer and the bipolar plate, serving as a pathway for water supply, gas emission, and electron transport, directly affecting the concentration polarization and Ohmic polarization of the water electrolysis reaction. The porous transport layer should have a rich continuous pore structure that is conducive to the diffusion and transfer of water and precipitated gases, as well as good conductivity to reduce Ohmic polarization. The anode side porous transport layer is generally made of corrosion-resistant titanium porous material in high potential acidic environments, and its surface can be treated with precious metal coating to reduce contact resistance and service life.
