Beschreibung
Zusammenfassung:A cathode layer and a membrane electrode assembly of solid oxide fuel cell are provided. The cathode layer consists of a plurality of perovskite crystal films, and an average change rate of the liner thermal expansion coefficient of these perovskite crystal films is 5% to 40% along a thickness direction. The membrane electrode assembly includes above cathode layer, and the liner thermal expansion coefficient of these perovskite crystal films decreases towards a solid electrolyte layer of the membrane electrode assembly.
