Sintered  titanium felts are primarily used in electrolyzer single cells and stacks as the flow field or diffuser material, particularly on the oxygen (anode) side. Since electrolyzer hardwares cannot use carbon-based gas diffusion layers (GDLS) at the oxygen evolution electrode due to immediate oxidation of carbon to CO2 (if the medium is acidic) or carbonate ions (if the medium is basic) during the electrolysis reaction, platinized titanium felt becomes an ideal candidate as the diffusion medium and also provide electrical contact between the anode catalyst layer and bipolar plate or current collector component at the anode side. Our platinized titanium felts are produced from titanium fibers that has been compressed to flattened form and annealed, ensuring a smooth, flat surface suitable for use in electrolyzer and have gone through our proprietary platinization process to extend the lifetime of titanium fiber felt greatly.
