摘要： In order to provide a membrane (100) for a membrane-electrode assembly (MEA) of a fuel cell, comprising two partial membranes (200, 300), which allows for a simpler water circuit compared to the prior art, it is proposed that the partial membranes (200, 300) have different ion exchange capacities (IECs) and/or one partial membrane (200) consists of a perfluorosulfonic acid polymer (PFSA) and the other partial membrane (300) consists of a sulfonated hydrocarbon polymer (HC). Optionally, the membrane can contain a porous carrier film (600). Moreover disclosed are a method for producing the membrane (100) as well as a membrane-electrode assembly and a fuel cell.
