The most cost effective, higher catalyst loading Gas Diffusion Electrode.  At 2.0 mg/cm² of Platinum Black, this GDE has 4-times the loading of the standard loading and is used in Fuel Cells and electrochemical systems requiring higher performance levels than can be reached with the lower loadings of supported catalysts.  This electrode is perfect for Hydrogen/Air Fuel Cell applications where the extra cost of the higher loading GDE may not be justified. 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.
