Nickel fiber felt is a specially manufactured felt composed of micron-level pure nickel fibers. The production process involves a unique felting technique and an ultra-high-temperature vacuum sintering process. In comparison to nickel mesh or nickel sintered porous plates, nickel fiber felt offers distinctive advantages. It features a well-defined three-dimensional mesh structure with high porosity, a large specific surface area, uniform distribution of pore sizes, excellent corrosion resistance, good water permeability, effective heat dissipation, high current density, low voltage requirements, stable performance, and an extended service life.

The high porosity nickel fiber felts are developed using chemical processes and metallic nickel fibers. This innovative material possesses characteristics such as lightweight, flexibility, adjustable porosity, and a felt-like texture.

Nickel fiber felt finds widespread applications in various industries such as fuel cells, military, aerospace, civil, medical, as well as for insulating materials, gaskets, heat insulation panels, and mechanical components. Specifically, it is extensively used as a hydrogen fuel cell diffusion media in the anode diffusion layer (GDL) of proton exchange membrane (PEM) water electrolysis.
