Abstract

Es wird eine Polymerelektrolytmembran-Brennstoffzelle mit einer Membran-Elektroden-Anordnung vorgeschlagen, in deren Gasdiffusionselektrode eine hydrophil und nanoporös ausgebildete Katalysatorschicht an eine hydrophob und nanoporös ausgebildete Gasdiffusionslage angrenzt. Die Leistung der Polymerelektrolytmembran-Brennstoffzelle ist in nur geringem Maße von einer Änderung der thermodynamischen Parameter, insbesondere der relativen Feuchte der Reaktionsstoffe, abhängig.
