XICAT™ Membrane Electrode Assemblies (MEA) are highly durable and they provide ultra-high performance assemblies for use in electrochemical applications due to the use of ultra-thin composite membranes.
MEA PEM-Aquivion-720-20μm-0.5mgPt-Cloth product is comprised of the following sub-components: 20 micrometers thick PEM-Aquivion (EW 720) composite membrane and carbon cloth based gas diffusion electrodes with 0.5 mg/cm2 loading of 60% Pt/C catalysts both for anode and anode.
Xergy has the largest 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. 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.
|Active Area||Membrane Area|
|2.2cm x 2.2cm||10.0cm x 10.0cm|
|5.0cm x 5.0cm||10.0cm x 10.0cm|
|7.1cm x 7.1cm||13.0cm x 13.0cm|
|10.0cm x 10.0cm||13.0cm x 13.0cm|
These are developmental products that are currently being offered to researchers for their various electrochemical applications and hence, the amount of experimental data is is scarce and Xergy team hopes that customers purchasing these products would provide some feedback in order to further improve their electrochemical performances.
Please note that a current lead time of 4 - 6 weeks is to be expected.
