Abstract:

In this paper, the visualized test platform of single fuel cell and the water balance model are used to investigate the relationship between the performance and the water content of proton exchange membrane fuel cell and their influencing factors. Firstly, the water balance model of fuel cell is given. Then, the visualized test platform for single fuel cell is constructed. Finally, the effects of the temperature and humidity of inlet air and the stoichiometric ratio of hydrogen and air on the electrochemical impedance spectroscopy, voltage and water content of fuel cell are tested with their influencing factors analyzed.

Key words: PEMFC, water balance model, visualized test platform, water content, performance
