The sintered nickel felt in GDL in PEM

In compliance with international technical requirements, nickel fiber felt is manufactured from micron-level pure nickel fiber using a specific felt layering method and an ultra-high temperature vacuum sintering process.

Strong corrosion resistance, wide specific surface area, homogeneous pore size distribution, high porosity, good water permeability, good heat dissipation, stable performance, and a long service life are all characteristics of nickel fiber felt.

In the fuel cell, military, aerospace, commercial, medical, and other industries, nickel fiber felt is frequently utilized. In specifically, proton exchange membrane (PEM) water electrolysis uses hydrogen fuel cell diffusion media as the gas diffusion layer (GDL).
