摘要：
In order to enhance the uniformity of fuel distribution and capability of liquid water management in the proton exchange membrane fuel cells (PEMFCs), a novel honeycomb-like flow field based on bionic structure was proposed. Firstly, a three-dimensional multiphase flow non-isothermal geometric model was constructed based on the honeycomb structural features, and the mathematical model of PEMFCs was established. Secondly, the model was verified for irrelevance and validity by using the computational fluid dynamics Fluent software. The cell performance and fuel distribution of the honeycomb-like flow field and the conventional parallel flow field were simulated and analyzed. Finally, the effectiveness of the honeycomb-like flow field design was verified by comparing the polarization performance, gas flow velocity distribution, fuel and liquid water component concentration and current density distribution. The results show that the peak power density of the cell with honeycomb-like flow field is 15.6% higher than that of the conventional parallel flow field, which is superior to parallel flow field in internal water management and fuel distribution. Compared with the honeycomb-like flow field with upper intake, the honeycomb-like flow field with left inlet exhibits more uniform gas pressure in the gas passage, which can effectively avoid local eddy current in the flow passage, and its peak power density can reach 0.393 3 W/cm2. © 2024 Central South University of Technology.
