“…Proton exchange membrane fuel cells (PEMFCs) are considered one of the most promising clean energy conversion devices and are widely used in transportation, stationary, auxiliary, and portable applications. [1][2][3] Operating parameter, 4 design of flow channel, 5,6 and species transport 7 are important issues to maintain the high performance and stable operation of a PEMFC. Among them, water management is the key of fuel cell technology because of its coupling with thermal management and close relation with electrochemical reaction of the system.…”

Water management is an important issue to be addressed to maintain the stable and efficient operation of a proton exchange membrane fuel cell (PEMFC).Gas purging is commonly performed to remove accumulated water in a PEMFC, especially in a dead-ended fuel cell system. A 3D dynamic model with a user-defined inlet boundary condition is proposed to study the effect of gas purging with different purge durations in an H 2 /O 2 PEMFC. The results show that the performance immediately deteriorates and then recovers to the original level during gas purging. Purging has a significant effect on the flow and mass transfer in the flow channel, and it leads to efficient removal of water from the PEMFC. The voltage variation tendency is consistent with the water content of the membrane. Membrane dehydration is the main reason for the performance degradation. Notable variations could be observed with increments in the purge duration. Water in a PEMFC is more sensitive and responsive to changes of operating conditions than the reactants. In addition, the performance is significantly deteriorated at a higher operating temperature. A large amount of water is removed during the gas purging, resulting in low water content in the membrane and low water saturation at the interface between the flow channel and the gas diffusion layer.

“…Numerous studies describe the advantages and disadvantages for different kinds of bipolar plates and flow channel configurations, being parallel, serpentine and interdigitated geometries the most habitually studied [7][8][9][10][11][12]. Furthermore, there are many works where the impact of the variation of different parameters related to the architecture of cells are studied and optimized to improve the design of the gas flow channels [12][13][14][15][16][17].…”
