The gas diffusion layer (GDL) is a key component in the proton exchange membrane electrolysis cell (PEMEC), which is located between the catalytic layer and the current field with many functions. To ensure minimum voltage, current, heat, interface and fluid loss, it must have characteristics such as electrical conductivity, thermal conductivity, corrosion resistance performance, high porosity and high permeability in order to efficiently transfer electrons, heat and reactants/products between the catalyst layer and the current field.
Titanium fiber felt, an excellent diffusion layer material that meets these requirements, is made of titanium fiber and has a porosity of more than 70%, providing ample space for the reaction. Our titanium fiber felt is manufactured with advanced technology, which can meet the needs of different applications and improve the performance and service life of hydrogen production in PEMEC.
Boegger titanium fiber felt is optimized for the following:
Specifications of Titanium Fiber Felt:
What is the main functions of GDL in PEMEC?
Where can the GDL be used?
Requirements for GDL in PEMEC:
Considering the above information, titanium fiber felt has received considerable attention as a highly promising material for PEMEC due to its high corrosion resistance at high positive overpotential, even in highly acidic and humid conditions. In addition, titanium provides high thermal conductivity, high electrical conductivity and excellent mechanical properties.
