TOPTITECH's 0.5mm Thickness Porous Titanium felt-plate Composition Sheet represents an advanced composite material engineered for high-efficiency gas diffusion layers in hydrogen electrolyzers. This hybrid structure integrates sintered titanium fiber felt with porous titanium plate through precision diffusion bonding, achieving optimal porosity gradients and interfacial conductivity. The titanium felt side facilitates turbulent gas flow distribution while maintaining low electrical contact resistance, whereas the sintered porous plate side provides mechanical stability and controlled permeability. Its unique dual-phase architecture ensures uniform current density distribution across the electrode surface, critical for preventing hot spot formation during prolonged PEM electrolysis operations.

Titnaium felt side

Designed specifically for oxygen evolution reaction environments, the 0.5mm Thickness Porous Titanium felt-plate Composition Sheet exhibits exceptional corrosion resistance against acidic anodic conditions. The sintered titanium matrix minimizes ionic transport losses while the interconnected pore network enhances bubble detachment kinetics. This configuration demonstrates superior performance over conventional carbon-based diffusion layers by eliminating oxidative degradation risks. Plasma-sprayed platinum coatings can be optionally applied to further enhance catalytic activity and long-term durability in demanding electrolyzer stack configurations.

Products Features

05mm Thickness Porous Titanium felt-plate Composition Sheet 2

Bipolar Conductivity Optimization

While the fiber felt layer optimizes interfacial contact with catalyst coatings and lowers charge transfer resistance across the electrode-electrolyte boundary layer, the sintered titanium plate substrate guarantees uniform current distribution.

Oxidation-Resistant Anode Performance

Unlike carbon-based materials, the monolithic titanium structure withstands high-potential oxygen evolution environments without corrosive degradation or dimensional instability.

Enhanced Mass Transport Dynamics

Graded porosity between the dense sintered plate and fibrous layer accelerates bubble detachment and electrolyte diffusion, critical for maintaining steady-state electrolyzer operation.

Mechanical-thermal Stability

Diffusion-bonded interfaces prevent delamination during thermal cycling, while the titanium matrix maintains structural integrity under compressive stack assembly forces.

Surface Modification Readiness

The open-fiber network readily accepts plasma-sprayed platinum or iridium oxide coatings for catalytic activation without compromising base material porosity.
