Description

technical field

[0001] The invention relates to a preparation method of a catalyst, more particularly to a preparation method of a Pt / C catalyst for a proton exchange membrane fuel cell. Background technique

[0002] Proton Exchange Membrane Fuel Cell (PEMFC) is a reaction device that directly converts the chemical energy of fuel and oxidizing gas into electrical energy through electrochemical reaction. It has the advantages of low working temperature, high energy conversion efficiency, simple structure, low noise, abundant fuel sources, and no environmental pollution. power supply. Proton exchange membrane fuel cells have attracted great attention from all over the world. As the key material of proton exchange membrane fuel cells, Pt / C catalyst has always been a hot spot in the research of proton exchange membrane fuel cells.

[0003] At present, Pt / C catalyst is a more practical catalyst for proton exchange membrane fuel cells. However, how to further improve the catalyt...
