As a high-performance porous material, Nickel fiber sintered felt is widely used in various preparation methods in the process of hydrogen production by water electrolysis. Its unique structure and material properties significantly improve the efficiency of hydrogen production and the stability of equipment.
Advantages
- Nickel fiber sintered felt has a three-dimensional porous structure. Porosity is more than 80%, which enhances the efficiency of catalytic reaction
- Rapid electrolyte penetration and hydrogen/oxygen bubbles can escape quickly, reducing concentration polarization
- Uniform current distribution: avoid local overheating or current concentration, and improve equipment safety
- Good electrical and thermal conductivity: high pore mass transfer efficiency, high electrical and thermal conductivity. Nickel sintered felt has become the first choice for efficient energy transmission.
- High mechanical strength: It can be given high mechanical strength under the sintering process, can withstand vibration and pressure fluctuations during electrolysis, and can last for more than 100,000 hours in high-voltage electrolyzers.
- Strong corrosion resistance and high temperature resistance: Strong corrosion resistance, can operate normally in high temperature environment
- High specific surface area: The specific surface area of sintered felt is much higher than that of traditional nickel mesh, and can be directly used as a catalyst carrier, reducing the use of precious metals and reducing costs
