Dynamic behavior is one of the most critical issues for proton exchange membrane fuel cells.
Purpose
2
This study aims to understand the dynamic characteristics which is conducive to the rational design and control of fuel cells.
Methods
2
In this paper
a simplified modeling of the direct channel proton exchange membrane fuel cell is carried out
and the appropriate parameters are selected for numerical calculation. Response of fuel cells is analyzed in different load time and load amplitude numerically.
Results
2
The trend curves of loading amplitude
loading time and reaction gas concentration are obtained.
Conclusion
2
The results show that it is beneficial to improve the stability of fuel cell by increasing the load time and decreasing the load amplitude. And it takes less time to reach stability for the cathode than the anode when the load is changed.
