| 英文摘要 | purge operation is an effective way to remove the accumulated liquid water in the anode of proton exchange membrane fuel cells (pemfcs). this paper studies the phenomenon of the two-phase now as well as the pressure drop fluctuation inside the flow field of a single cell during the purge process. the flow patterns are identified as intermittent purge and annular purge, and the two purge processes are contrastively analyzed and discussed. the intermittent purge greatly affects the fuel cell performance and thus it is not suitable for the in situ application. the annular purge process requires a higher pressure drop, and the critical pressure drop is calculated from the annular purge model. furthermore, this value is quantitatively analyzed and validated by experiments. the results show that the annular purge is appropriate for removing liquid water out of the anode in the fuel cell.
