Titanium fiber felt, a diffusion layer material, provides electrons between the catalyst layer and the bipolar plate or the current distributor on the anode side. Due to its three-dimensional network porous structure, high porosity, high corrosion resistance and other characteristics, titanium felt has become one of the best materials of diffusion layer in fuel cell and hydrogen production by water electrolysis.

Carbon based materials, typically used in LGDL of PEMFCs. Such as graphite bipolar plates, carbon paper, and carbon cloth. But, they are unsuitable in the anode of LGDL, due to the high anodic potential that occurs during electrolysis operation.That because it will create a highly oxidative environment, which corrodes the carbon and results in poor interfacial contacts. Then, the efficiency of the cell will decrease. In order to resolve this issue, materials (titanium felt) with a high corrosion resistance is necessary.
