Product Overview
DiffuCarb™ E003 · DiffuCarb™ E003PT · Pt-IrOx Composite Electrode
DiffuCarb™ E003 Pt-IrOx Chemically Coated on Carbon Paper and DiffuCarb™ E003PT Pt-IrOx Chemically Coated on Platinized Carbon Paper combine a Pt-IrOx composite catalyst layer with a porous conductive substrate. The composite architecture is intended to integrate Pt-assisted electron transfer and interfacial conductivity with the OER catalytic activity and stability associated with IrOx.
Pt-IrOx Composite Layer
The supplied description positions the composite layer for enhanced OER activity, electron transfer and stability.
E003 · Raw Carbon Paper
Uses TGPH060 raw carbon paper by default for conductivity, porous transport and mechanical support.
E003PT · Platinized Carbon Paper
Uses TGPH060P platinized carbon paper by default, with 0.1 mg/cm² Pt on the substrate.
