Description

Technical field

[0001] The invention belongs to the technical field of fuel cell electrode material preparation, and in particular relates to a method for preparing a highly efficient composite cathode material for fuel cells. Background technique

[0002] Fuel cell is an electrochemical power generation device that can efficiently and cleanly convert fuel chemical energy into electrical energy. Among them, solid oxide fuel cell (SOFC) has unique advantages, such as the use of all-solid ceramic devices, which will not cause electrolyte corrosion , Leakage phenomenon; modular design can also be adopted, reducing design and production costs. The cathode is an important component of the SOFC, and the performance of the SOFC is closely related to the catalytic activity, conductivity and microstructure of the cathode. The ideal high-performance cathode needs to have excellent electrochemical catalytic activity, high electrochemical reaction area, and good electronic conductivity and ...
