DiffuCarb™ E254c PtRu/HSC Carbon Paper Electrode
MGL370 · PtRu/HSC · Nafion · Direct Methanol Fuel Cell
The DiffuCarb™ E254c PtRu/HSC Carbon Paper Electrode (MGL370) is a high-performance electrode specifically engineered for use in Direct Methanol Fuel Cells (DMFC). The electrode uses a platinum-ruthenium (PtRu) alloy catalyst supported on high-specific-surface-area carbon and uniformly coated on an MGL370 carbon paper substrate.
Nafion is used as the binder to secure the catalyst layer and support proton conduction. The PtRu catalyst is positioned for the methanol oxidation reaction (MOR), making E254c suitable for DMFC research, MEA development and methanol-based electrochemical power systems.
