Effective water removal and transport in the flow channel is significantly important to the critical water management in proton exchange membrane fuel cells (PEMFCs). In this work, we proposed a fin‐shaped flow channel with hydrophobic walls to enhance liquid water removal from the surface of gas diffusion layer (GDL). Computational fluid dynamics simulations with volume‐of‐fluid method were carried...
Effective water removal and transport in the flow field is significantly important to the critical water management in proton exchange membrane fuel cells (PEMFCs). In this work, a slope turn was proposed in the hydrophobic channel of the multi‐serpentine flow field, and the transport and dynamics of water in the modified flow channel were numerically investigated with the volume‐of‐fluid method....
The flow field on bipolar plate of proton exchange membrane fuel cells (PEMFCs) plays a decisive role in cell performance. In this work, two compensated flow fields, termed separated multi‐serpentine flow field and combined multi‐serpentine flow field, were investigated to understand their effects on cell performance, flow uniformity and water removal capability. The results show that the compensated...
