Application of Violet Tungsten Oxide in Fuel Cell Catalyst

Fuel cell is a chemical equipment that convert chemical energy into electricity, which is the most promising power generation technology from the perspective of saving energy and protecting the ecological environment.

Due to the continuous development of environmental protection industry in our country, the energy supply mode of fuel cells instead of the original chemical fuel is gradually developed, and the corresponding researches on fuel cells are also being carried out.

In the fuel cell electrode reaction process, the proton exchange membrane between the electrodes on both sides played a decisive role. The adsorption and poisoning of compounds on the Pt-based catalyst surface will bring negative and fatal effects on the performance of PEMFCs. Through a series of latest research shows that the use of violet tungsten oxide modified precious metal catalyst can make the Pt electrode and violet tungsten oxide electronic exchange occurs, while making the catalyst to obtain a better anti-sulfur effect.
