Ti-Based Gas Diffusion Layer anode titanium GDL

Ti-Based Gas Diffusion Layer anode titanium GDL

Metal porous titanium plates are primarily used in standard PEM electrolyzer single cells and stacks as the flow field or diffuser material, particularly on the oxygen (anode) side. .  Electrolyzer hardwares cannot use carbon-based gas diffusion layers (GDLs) at the anode because the carbon will immediately oxidize to CO2 (if the medium is acidic) or carbonate ions (if the medium is basic) during the reaction.

Porous titanium plates are an excellent option for a diffusion medium in various applications, including electrolyzers and fuel cells. TOPTITECH's porous metal gas diffusion layers are the top choice for achieving high performance in these applications. The uniform porosity, strength, and corrosion resistance outperform other diffusion layer productsTOPTITECH substrates are available in a variety of alloys to support a full range of fuel cell operating temperatures, and can be coated with surface treatments or catalyst layers to enchance performance.

In an electrolyzer, why not utilize a carbon-based Gas Diffusion Layer?

Using a carbon-based gas diffusion layer (GDL) in an electrolyzer can pose several challenges. The presence of oxygen ions and voltage on the anode side of the electrolyzer can cause the carbon in the GDL to be oxidized, resulting in the generation of CO2 gas. While this can initially lead to a lower electrolysis voltage, the consumption of the carbon GDL is a short-lived phenomenon. As a result, the stack compression decreases, leading to higher resistance and lower performance. Therefore, it is not advisable to use a carbon-based GDL in an electrolyzer.
