Product Description

Titanium Fiber Felt for PEM Hydrogen Production Anode Diffusion Layers

Hydrogen serves as a clean, renewable green energy source, and Proton Exchange Membrane water electrolysis (PEMWE) represents one of the primary methods for hydrogen production. This technology utilizes proton exchange membrane (PEM) as a solid electrolyte, replacing alkaline electrolytes and diaphragms while using pure water as the electrolyte medium.

In PEM water electrolysis hydrogen production systems, the membrane electrode assembly—comprising the diffusion layer (Gas Diffusion Layer, GDL), catalytic layer, and proton exchange membrane—serves as the main site for electrochemical reactions and constitutes the core component of PEMWE technology.

Gas Diffusion Layer Functions

The Gas Diffusion Layer (GDL) performs multiple critical functions including supporting the Catalyst Coated Membrane (CCM), evenly distributing reaction water, efficiently discharging generated gases, conducting electrical current, and serving as a key component influencing electrolyzer performance.

Optimal Diffusion Layer Characteristics

Excellent electrical and thermal conductivity to maintain low contact resistance between electrode catalysts and reduce electrolysis overpotential
Strong acid corrosion resistance with anode diffusion layers exhibiting oxidation corrosion resistance for oxygen evolution reactions
Porous and elastic structure capable of supporting membrane electrodes under pressure
Extended service life and cost-effective manufacturing
