Titanium Fiber Felts for PEM water electrolysis, while nickel felts for AEM & ALK water electrolysis.
There are some differences in the types of electrolyzers in which titanium fiber felt and nickel fiber felt are applied. The specific details are as follows:
– **Titanium fiber felt**: (Grade 1 Titanium material metal felts )
It is mainly applied to proton exchange membrane (PEM) electrolyzers as a gas diffusion layer material. In PEM electrolyzers, the titanium fiber felt has many advantages. For example, it has excellent corrosion resistance in a strongly acidic and highly oxidizing working environment. Its three-dimensional reticular porous structure can provide a large specific surface area, which is beneficial for gas diffusion and liquid circulation. It can reduce the ohmic resistance and overpotential, thereby improving the electrolysis performance. In addition, it can also be used in the gas diffusion layer of PEM electrolyzers in some devices related to PEM electrolyzers, such as hydrogen generators, oxygen concentrators, hydrogen-rich water machines, etc.
– **Nickel fiber felt**:(Nickel 200/201 material nickel sintered felts)
It is mainly applied to anion exchange membrane (AEM) electrolyzers and alkaline (ALK) electrolyzers. In AEM electrolyzers, the nickel fiber felt can serve as a gas diffusion layer. Thanks to the stability of nickel metal and the continuous three-dimensional structure of the fiber felt, it can exhibit good passivation ability on the anode side of the AEM electrolyzer, resist the corrosion of alkaline solutions, and have good contact with the anion exchange membrane, reducing the contact resistance. In ALK electrolyzers, the nickel fiber felt can be used as an electrode material. Compared with traditional nickel mesh and nickel foam electrodes, it has advantages in terms of thickness, pore size, unit weight, porosity, etc. It has characteristics such as a large specific surface area, high tensile strength, and good flexibility, which can improve the performance of the electrode.
In summary, the titanium fiber felt plays an important role in PEM electrolyzers, while the nickel fiber felt is widely used in AEM electrolyzers and ALK electrolyzers. Each of them, with its own characteristics, contributes to the performance improvement of different types of electrolyzers.
