Research on hydrogen-oxygen fuel cell model

With the development of society and the progress of science and technology, energy plays an important role in human production and life.Hydrogen energy is a high calorific value, low pollution and renewable energy.Recent years,in order to achieve peaking carbon dioxide emissions and carbon neutrality goals, the use of hydrogen energy is increasingly important.Hydrogen-oxygen fuel cell is widely used,compared with primary batteries and crude oil, it has less pollution to the environment and is a green, clean and efficient energy,therefore, it has a very good prospect of development and application in today's decreasing fossil fuels and energy crisis.In this paper, the hydrogen-oxygen fuel cell is taken as the research object, and the model of the fuel cell stack is established. On the basis of the model, the polarization characteristics,dynamic response characteristics and the factors affecting the stack voltage output of the fuel cell are studied. The simulation results show that the output curve of the model is similar to the actual measurement, and the dynamic characteristics are good.
