High Purity Ti Fiber Felt Titanium Fiber Felt for Water Electrolyzer

Introduction

Ti fiber felt is mainly used as a flow field or diffuser material for electrolytic cells and stacks, especially on the oxygen (anode) side. Due to the immediate oxidation of carbon to CO2 (if the medium is acidic) or carbonate ions (if the medium is alkaline) during the electrolysis reaction, the hardware of the electrolysis cell cannot use a carbon based gas diffusion layer (GDL) on the oxygen evolving electrode. Therefore, platinum coated titanium felt is an ideal candidate for diffusion medium and also provides electrical contact between the anode catalyst layer and the bipolar plate or collector component on the anode side. Our platinum plated titanium felt is made of titanium fibers, which are compressed into a flat form and annealed to ensure a smooth and flat surface. It is suitable for electrolytic cells and has undergone our proprietary platinum plating process, greatly extending the service life of the titanium fiber felt.
