Platinum based Gas Diffusion Electrodes (GDE) are the standard electrodes used for Hydrogen / Air Fuel Cells (PEMFC), Direct Methanol Fuel Cells (DMFC), Microbial Fuel Cells (MFC), and many more applications. The Platinum base is generally applied to a Gas Diffusion Layer (GDL) that has a Micro-Porous Layer (MPL) and Teflon (PTFE) treatment.

Low Loading Electrodes (e.g. 0.03mg/cm², 0.3mg/cm², etc.) are designed for cost sensitive applications and are suitable for electrochemical systems needing low amounts of Platinum to support the reaction.

High Loading Electrodes (e.g. 2.0mg/cm², 4.0mg/cm², etc.) are designed for high performance and are typically used in applications where performance and efficiency are critical.
