Pure Titanium Electrode Porous Fiber Felts for PEM Fuel Cell

Pure TitaniumELectrodePOrousFiberFElts, also known as ti felts or ti fiber felts, are commonly used in electrolyzer stacks as the diffusion layer or flow field material on the oxygen (anode) side. Unlike carbon-based gas diffusion layers that cannot be used at the oxygen evolution electrode due to immediate oxidation, titanium fiber felt is an ideal diffusion medium that provides electrical contact between the anode catalyst layer and bipolar plate or current collector component. Its unique properties, including high porosity and uniform pore size distribution, enable efficient gas transport and water management within the cell, enhancing the overall efficiency of the electrolysis process. Overall, the use of titanium fiber felt in electrolyzer stacks improves their durability, reliability, and efficiency in hydrogen production.
