Nickel fiber felt is made of micron-level pure nickel fiber in accordance with foreign technical standards, through special felt laying process and ultra-high temperature vacuum sintering process.

Compared with nickel mesh or nickel powder sintered plate, nickel fiber felt has excellent three-dimensional network porous structure, high porosity, large specific surface area, uniform pore size distribution, strong corrosion resistance, good water permeability, good heat dissipation and stable performance, long life and other advantages.

In the whole production process, fiber drawing is a key step. Compared with melt spinning, mechanical cutting, monofilament drawing and other methods, the preparation technology adopted by cluster drawing has the advantages of uniform wire diameter, easy continuous production and low cost. A number of technical problems in the cluster drawing process have been solved. Nickel fibers with different wire diameters from 6 μm to 40 μm can be produced to meet the requirements of nickel fiber mats with different properties. The shearing of the fiber is carried out on a special cutting machine, which can be cut into different specifications such as 33 mm in length. It has the characteristics of uniform shearing length and high production efficiency. The nickel fiber is laid into a net by the air flow method, and the equipment used is an imported felt laying unit. By adjusting various complex process parameters, the laid nickel fiber net has good uniformity and no defects such as bundled fibers and fiber agglomeration, and the single weight can be controlled as needed.

Nickel fiber felt is widely used in fuel cells, military, aerospace, civil, medical and other industries. In particular, hydrogen fuel cell diffusion media, used in the anode diffusion layer (GDL) in proton exchange membrane (PEM) water electrolysis.

Aida can produce nickel fiber felts of various specifications and performances according to customer requirements.
