Porous Titanium Metal Fiber Felt PEM Electrolytic Cell Gas Diffusion Layer Material

Porous titanium gas diffusion layer in PEM electrolytic cell

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

Specification parameters

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;
5. Excellent electrical and thermal conductivity;
6. High temperature resistance and thermal shock resistance;
7. Resistance to medium corrosion;
8. Weldable and machinable

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:

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.
