Titanium Fiber Felt for PEM& AEM Electrolysis stack and Fuel cell LGDL 

Titanium Fiber Felt for PEM Electrolysis stack and Fuel cell LGDL

Titanium fiber felt is suitable for LGDL (liquid/gas diffusion layer) in hydrogen production and Fuel cell stack.

As a highly promising material for a PEM electrolyzer, titanium fiber felt provides high thermal/ electrical conductivities and excellent mechanical properties. For example, high corrosion resistance at high positive overpotential, even in highly acidic and humid conditions.

Carbon based materials, are typically used in LGDL of PEMFCs. Such as graphite bipolar plates, carbon paper, and carbon cloth. While, they are unsuitable in the anode of LGDL, due to the high anodic potential that occurs during electrolysis operation as they 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 are required.
