XICATâ¢ Membrane Electrode Assemblies (MEA) are highlydurable and they provide ultra-high performance assemblies for use inelectrochemical applications due to the use of ultra-thin composite membranes.
MEA PEM-Dyneon-725-05Î¼m-0.5mgPt-Cloth product iscomprised of the following sub-components: 5 micrometers thick PEM-Dyneon (EW725) composite membrane and carbon cloth based gas diffusion electrodes with0.5 mg/cm2 loading of 60% Pt/C catalysts both for anode andanode.
Xergy has the largest selection of composite protonexchange membranes (C-PEM) and proton exchange ionomers (PEI) and compositeanion exchange membranes (C-AEM) and anion exchange ionomers (AEI) to selectfrom for the XICAT MEA design. C-PEMs/PEIs for the XICAT MEAs are availablefrom Dyneonâ¢, Aquivionâ¢, and Nafionâ¢ perfluorosulfonic acid (PFSA)ionomers. C-AEMs/AEIs are available from Durionâ¢ and Pentionâ¢ionomers. The standard MEA is a 5-layer construction with a membrane sandwichedbetween a gas diffusion electrode and catalyst layer. A second MEA structure isa 3-layer construction known as a catalyst coated membrane (CCM), in which thecatalyst is applied directly to the membrane and there is no gas diffusionlayer.
