Flow field designs for the bipolar plates of the proton exchange membrane fuel cell are reviewed; including the serpentine, parallel, interdigitated, mesh type or their mixtures, furthermore 2D circular and 3D tubular geometries, porous, fractal, and biomimetic flow fields. The advantages/disadvantages and tendencies from field optimizations are discussed. The performance of each flow field design is compared to the conventional serpentine flow field. Good flow field plates give uniform gas distributions, low pressure drop for transport, and sufficient rib area to provide high electronic conductivity. A good field should also prevent water condensation, remove water efficiently, and provide sufficiently high moisture content in the membrane. The demands on design are sometimes contradictory. Future work should aim for a flow field geometry and topology that produces uniform gas delivery at a low pressure-drop, and at the same time has an optimal channel shape for better water removal. It is concluded that for an area-filling gas distributor, the developments should aim to find a flow field in accordance with minimum entropy production, making an emphasis on multi-criteria optimization methods.

“…[75][76][77] Bioinspired flow field patterns due to their branching networks or porous structures provide large surface areas functioning as heat sinks to avoid localized hotspot formations. [78][79][80] Several researchers studied the bioinspired-based flow field design, including leaf vein and lung-based structures, through CFD simulations for PEMFCs. These studies report an overall improvement in performance, uniformity in gas flow distribution, as well as easy removal of excess products for the biomimetic designs compared with the conventional FFPs.…”

“…However, the ever-growing power density of the PEMFC system imposes great demands that current cooling methods become difficult to meet. Therefore, the improvement of thermal management has become one of the main focuses in fuel cell research [31][32][33][34]. For instance, Afshari et al [35] performed a three-dimensional numerical simulation to investigate the effect of coolant flow channel shape on water-cooled PEMFC's cooling performance and the results showed that zigzag flow channels can improve the cooling performance by reducing maximum surface temperature and surface temperature difference.…”

Thermal management is considered a critical issue in proton exchange membrane fuel cells (PEMFCs), since it not only influences the cell performance but also impacts PEMFC's reliability and durability. With the ever-increasing power density of PEMFC, traditional cooling approaches including air cooling and water cooling become difficult to meet the demand for highpower heat dissipation. Therefore, phase-change cooling is proposed for fuel cell application in this work, and the potential advantages are discussed and demonstrated via a mathematical model incorporating phase-change heat transfer. The thermal management performance is evaluated by temperature uniformity, maximum temperature difference, and the cooling capacity to compare the difference between phase-change cooling and traditional methods, which demonstrates that phase-change cooling owns a greatly improved thermal management performance. In addition, a simple method to broaden the operating temperature of phase-change cooling based on one certain coolant is offered, which is pressurizing in the coolant channel to regulate the boiling temperature that could further improve the application feasibility of phase-change cooling strategy in fuel cells.
