Product Overview
DiffuCarb™ E004 · DiffuCarb™ E004PT · RuOx Chemical Coating
DiffuCarb™ E004 RuOx Chemically Coated on Carbon Paper and DiffuCarb™ E004PT RuOx Chemically Coated on Platinized Carbon Paper combine a RuOx catalytic layer with a porous conductive substrate. The main difference lies in the substrate: E004 uses raw carbon paper, while E004PT uses the corresponding platinized carbon paper.
RuOx Catalyst Layer
The supplied product description positions RuOx as a highly active OER catalyst for water-electrolysis and related electrochemical studies.
E004 · Carbon Paper
Uses conductive porous carbon paper for electron transport, mass transfer and mechanical support.
E004PT · Platinized Carbon Paper
Adds a Pt-coated interface to enhance conductivity and durability positioning under demanding conditions.
