The 4.0mg/cm² Platinum Ruthenium on Carbon Paper is the most popular Gas Diffusion Electrode (GDE) for use in Direct Methanol Fuel Cells (DMFC). The Platinum Ruthenium (PtRu) catalyst is designed to facilitate the Methanol reaction to create an efficient DMFC.  The Gas Diffusion Layer (GDL) used is Sigracet 22 BB which is 215 microns thick. Other GDL materials are also available by custom request, as are custom sizes and loadings.

Includes a Nafion Post Coat for improved water management and adhesion to the membrane.
