Description

technical field

[0001] The invention relates to a transition metal copper nano-catalyst, in particular to a copper-based nano-catalyst used for fuel cell cathode oxygen reduction reaction and its preparation method and application. Background technique

[0002] Traditional power generation technologies mainly rely on the massive consumption of fossil fuels, causing serious environmental pollution, which greatly affects human life and health. A fuel cell is a device that directly converts chemical energy into electrical energy. Compared with the principle of dry batteries used in daily life, it solves the problems of dry batteries with limited volume, fast consumption, short life, and difficulty in recycling. In principle, as long as the fuel and catalyst are supplied to the fuel cell to make the electrochemical reaction continue, it can continuously transmit electric energy to the outside. Because the fuel cell directly converts chemical energy into electrical energy withou...
