Nickel felt is a high-performance porous material designed for advanced energy applications. This product features a custom size of 100*100*0.38 mm with a porosity of approximately 70%, specifically developed to meet the stringent demands of AEM electrolyzers.

Its ultra-thin 0.38 mm thickness not only optimizes the compact structure of the electrolyzer but also significantly enhances gas diffusion and reaction efficiency, making it an ideal choice for high-efficiency energy conversion systems.

The precise 0.38 mm design ensures maximum active area within a limited space while maintaining a high-porosity structure to promote uniform electrolyte distribution and rapid gas exhaust. This unique combination enables AEM electrolyzers to operate stably at high current densities, reducing energy consumption and extending service life.

Products Features

Custom Ultra-Thin Thickness

The 0.38 mm precise thickness is a core advantage tailored for AEM electrolyzers. This dimension improves proton and electron transport efficiency by shortening diffusion paths, while avoiding common voltage drop issues in thicker materials, ensuring high performance under high-pressure conditions.

Optimized Porous Structure

With approximately 70% porosity, it provides a continuous and uniform porous network that enhances the penetration of reactive gases and retention of liquid electrolytes. This not only increases the electrochemical active area but also reduces concentration polarization, resulting in a more stable and efficient electrolysis process.

Excellent Mechanical Stability

Despite the mere 0.38 mm thickness, this nickel felt maintains high strength and flexibility through advanced manufacturing processes, enabling it to withstand mechanical stress and thermal cycles in AEM electrolyzers without deformation or collapse, thereby ensuring long-term reliability.

High Chemical Compatibility

The nickel material itself offers outstanding corrosion resistance and conductivity, combined with the custom thickness to ensure stability in both alkaline and acidic electrolytes. This characteristic minimizes electrode degradation risks and suits diverse electrolyzer configurations.
