ELECTROCATALYST FOR FUEL CELLS AND METHOD FOR PRODUCING SAID ELECTROCATALYST |
摘要 |
The invention relates to a carbon-free electrocatalyst for fuel cells, containing an electrically conductive substrate and a catalytically active species, wherein the conductive substrate is an inorganic, multi-component substrate material of the composition 0X1-0X2, in which 0X1 means an electrically non-conductive inorganic oxide having a specific surface area (BET) in the range of 50 to 400 m2/g and 0X2 means a conductive oxide. The non-conductive inorganic oxide 0X1 is coated with the conductive oxide 0X2. The multi-component substrate preferably has a core/shell structure. The multi-component substrate material 0X1-0X2 has an electrical conductivity in the range > 0.01 S/cm and is coated with catalytically active particles containing noble metal. The electrocatalysts produced therewith are used in electrochemical devices such as PEM fuel cells and exhibit high corrosion stability. |
