Type of Cells MEA's & GDL

Xergy has a large selection of composite proton exchange membranes (C-PEM) and proton exchange ionomers (PEI) and composite anion exchange membranes (C-AEM) and anion exchange ionomers (AEI) to select from for the XICAT MEA design.
-  C-PEMs/PEIs for the XICAT MEAs are available from Dyneon™, Aquivion™, and Nafion™ perfluorosulfonic acid (PFSA) ionomers.
 -  C-AEMs/AEIs are available from Durion™ and Pention™ ionomers.

This MEA is a standard 5-layer construction with a membrane sandwiched between a gas diffusion electrode and catalyst layer.
A second MEA structure is a 3-layer construction known as a catalyst coated membrane (CCM), in which the catalyst is applied directly to the membrane and there is no gas diffusion layer.
The XICAT™ Membrane Electrode Assemblies (MEA's) are very durable and provide for ultra-high performance assemblies used in electrochemical applications due to the use of ultra-thin composite membranes.
