Gasdiffusionselektrode mit Katalysator für/eine elektrochemische Zelle mit Festelektrolyten und Verfahren zur Herstellung einer solchen Elektrode

摘要

Gas diffusion electrode with catalyst for an electrochemical cell with solid electrolyte, in particular for a fuel cell with solid electrolyte, which electrode contains a hydrophobic, porous back support (12), a non-catalytic intermediate layer (13) which contains electron conductive material and an active catalytic layer (14) which contains bound catalyst particles, characterized in that the intermediate layer (13) contains a mixture of electron conductive material and a proton conductive ionomer, and in that the active layer (14) forms the outside layer and the catalyst particles are bound by a proton conductive ionomer
