XICAT™ Membrane Electrode Assemblies (MEA) are highly customizable, ultra-high performance assemblies for use in electrochemical applications. Xergy has the largest selection of proton exchange membranes and ionomers (PEM/PEI) and anion exchange membranes and ionomers (AEM/AEI) to select from for MEA design. PEMs/PEIs available include Dyneon™, Aquivion™, and Nafion™ PFSA ionomers, and AEMs/AEIs available include Durion™ and Pention™ ionomers. The standard MEA is a 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. Custom MEAs with various membranes, loadings, catalyst types and electrode structures are available upon request. 7-layer MEAs with gasketing are also available upon request.
