Advantages

Pore-former-free

Solely adjusting Ti powder size optimizes pore structure, eliminating pore formers to simplify fabrication and enhance mechanical performance.

Outperforms commercial felt

The PTL with D₅₀ = 33 μm exhibits a cell performance enhancement at 2 A/cm² compared to commercial Ti felt PTL, due to optimal gas/water transport and electronic conductivity.

Applications

• PEM electrolyzer：Directly replace commercial Ti felt in electrolyzers and enhance performance.
• Water electrolysis for hydrogen production：Used in water electrolysis to improve efficiency at high current density.
