Platinum across the fiber surface.The Pt layer follows the accessible surface of the three-dimensional titanium network. It is a conformal interface coating—not a separate dense sheet that closes the pores. Ti fiber Platinum surface coating Sintered titanium-fiber core | A stable electrical interface for the anode PTL.In anode-side PEM operation, exposed titanium can develop a resistive oxide surface. Platinum helps limit this interfacial resistance while preserving the felt's water and oxygen transport pathways. The oxygen-evolution catalyst remains in the catalyst layer.
Pretreatment and adhesion matter. Surface cleaning and activation are coordinated with deposition so the thin platinum layer remains continuous and firmly bonded without sacrificing the felt's open pore structure. |
YIANTENG platinum-coating advantages.Controlled preparation and deposition create uniform, firmly bonded platinum coverage without closing the felt's pore network. | Stable conductivityThe Pt surface suppresses resistive oxide growth and helps maintain a low-resistance current path at the catalyst interface. Coating uniformityControlled deposition supports consistent platinum coverage across accessible three-dimensional fiber surfaces and reduces local weak points. Coating adhesionCleaning and surface activation promote a firmly bonded layer through cutting, handling, stack compression and operation. Open pores retainedThickness control limits excess metal buildup so the felt retains its interconnected pathways for water and oxygen transport. Reduced titanium passivationPlatinum limits exposure of the titanium surface and helps control resistance growth caused by oxide formation. |
