DiffuCarb™ E257c High Surface Area PtRu Black Electrode
MGL370 · PtRu Black · Anionic Binder · AEMFC / AFC / AEMWE
The DiffuCarb™ E257c High Surface Area PtRu Black-Carbon Paper Electrode (MGL370) is specifically designed for Anion Exchange Membrane Fuel Cells (AEMFC), Alkaline Fuel Cells (AFC), and Alkaline Water Electrolysis (AEMWE).
The electrode utilizes a high-surface-area PtRu Black catalyst that provides a large number of active sites for electrocatalytic reactions. The catalyst is integrated with porous MGL370 carbon paper, while an anionic binder is incorporated to improve ion transport and catalyst-layer cohesion under alkaline operating conditions.
High-Surface-Area PtRu Black
Provides a large catalytic surface for HOR, ORR and related alkaline electrochemical reactions.
CO-Tolerance Positioning
The Pt/Ru combination is used to reduce CO-poisoning effects on catalyst activity.
MGL370 Carbon Paper
Provides a porous, conductive platform for gas diffusion, electrical conduction and electrode support.
Anionic Binder
Supports alkaline ion transport and helps maintain catalyst-layer integrity.
