The Youveim® Titanium Fiber Paper, developed by SCI Materials Hub, is a high-performance diffusion medium specifically designed for water electrolysis applications. This material serves as an excellent alternative to traditional carbon paper in electrolyzer stacks, especially for the oxygen (anode) side, where oxidation of carbon-based materials is a critical concern. Youveim® Titanium Fiber Paper combines the durability of titanium with advanced manufacturing processes to meet the rigorous demands of electrolyzer technology.

Why Choose Titanium Fiber Paper?

In water electrolysis, carbon-based gas diffusion layers (GDLs) are typically unsuitable for the oxygen evolution electrode (anode) due to rapid oxidation under electrolytic conditions. Carbon materials are oxidized to CO₂ in acidic media or carbonate ions in alkaline media, leading to a shorter lifespan and compromised performance. Titanium fiber paper, with its superior oxidation resistance, is the ideal solution for the anode side diffusion layer.

Key Features of Youveim® Titanium Fiber Paper

1. Enhanced Conductivity and Short-Circuit Resistance
   Made from ultra-long 70mm titanium fibers, Youveim® Titanium Fiber Paper offers outstanding electrical conductivity while reducing the risk of fiber breakage and potential short circuits. The continuous structure of long fibers enhances conductivity, even under high current densities, making it a reliable choice for demanding applications.

2. High Current Density Endurance
   Utilizing coarse titanium fibers with a diameter of 25-50 μm, the material is structurally robust and able to support higher current densities. This design improves the material’s longevity and stability, making it suitable for long-term operation under high load conditions.

3. Superior Oxidation Resistance and Plating Compatibility
   The thicker titanium fibers exhibit excellent oxidation resistance, which helps maintain conductivity in high-oxygen environments. Additionally, the coarse fiber surface is well-suited for platinum or gold coating, providing a durable and robust plating layer that enhances electrochemical performance and extends the system’s operational life.

4. Platinized and Gold-Plated Options
   For applications requiring enhanced durability and conductivity, Youveim® Titanium Fiber Paper is available with platinum or gold plating. These coatings prevent the formation of electrically insulating titanium dioxide (TiO₂) on the surface, ensuring stable conductivity and reducing interfacial resistance in high-pressure electrolyzer systems.

5. High Porosity Design for Efficient Diffusion
   With a porosity range of 60-70%, Youveim® Titanium Fiber Paper facilitates optimal gas and electrolyte diffusion, ensuring uniform reaction distribution. This high porosity design enhances electrolysis efficiency and allows for rapid electrolyte transport.
