Abstract
The flow field is an important place for gas distribution and liquid water discharge, which plays a vital role in improving the performance of proton exchange membrane fuel cell (PEMFC). Liquid flooding is a thorny problem occurring in the flow field frequently. However, the appropriate flow field structure and operating condition can help solve flooding issue. In this paper, the PEMFC performance and the water discharging ability is obtained by variety of experiments in different serpentine flow field structures and relative humidity (including setting as 10%, 30%, 50% and 70%). This study provides a proposal is that using the anode plate with a double serpentine structure and conducted under the humidity condition as 30% can result in perfect water management and achieve the max power density value to 0.898 W/cm2.
