The concept of fuel cells was first proposed by British scientist G.R. Grove in 1839, and then in the middle of the 20th century, thanks to the advent of Nafion series membranes (DuPont, USA), the application of low-temperature proton exchange membrane fuel cell technology was realized. At present, fuel cells are an important branch of my country's new energy development strategy. As the cleanest application energy, fuel cells are the "ultimate solution" in the field of mobile energy. At present, Japan, Europe and the United States are the leaders in the development of global fuel cells, but the scale is limited and the production cost is declining slowly. We believe that China will really lead the industrialization of fuel cells in the future. At present, fuel cells are mainly divided into two categories: hydrogen fuel cells and methanol fuel cells. Hydrogen fuel cells mainly use hydrogen as the main driving force for battery kinetic energy, while methanol fuel cells mainly use synthesizable methanol as the motive force for generating electricity. difference.

       The main features of fuel cells are: clean and pollution-free, quiet and noise-free, flexible assembly, and strong environmental adaptability (especially in alpine regions, where conventional batteries such as lithium batteries cannot be used, the advantages of fuel cells are particularly obvious); With these characteristics, it has great application prospects in various occasions such as military industry, aerospace, maritime, agriculture, outdoor rescue and so on.
