“…Therefore, the model with N = 64 outlets produced a more uniform flow distribution at the lowest pressure drop and energy dissipation. The fractal system with 256 outlets was found to have the highest uniformity of the flow and consequently the current distribution (Ramos-Alvarado et al, 2011), but the overall PEMFC performance was lower than in the convenient parallel design (Fan et al, 2008;Lorenzini-Gutierrez et al, 2013;Ouellette et al, 2018).…”

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.

“…However, the study suggests that an improved performance is achievable for a fractal design at higher temperatures, which do not involve removing water in the liquid phase. Fractal tree‐like flow fields are characterized by their branching structures, and the effects of one, two, and three levels of bifurcation in fractal flow channels are reported by Lorenzini et al [ 45 ] The results reveal that an increase in the level of bifurcation substantially improves the peak power density, exhibiting a 25.25% increase for three‐level versus one‐level bifurcation fractal design. Aside from the level of bifurcation, there are other important parameters to be taken into account for optimal designing of fractal flow fields.…”

“…Researchers have enumerated multiple advantages of using www.advancedsciencenews.com www.advenergysustres.com bioinspired flow fields and compared their performance characteristics with other conventional flow field designs. [43][44][45][46][47][48][49][50] The flow field design is an intricate process that has to keep different factors and parameters in consideration to achieve optimal performance, such as the minimization of material requirement, uniform distribution of gases, effective water transport, and manufacturability. [51,52] Mathematical models are extensively used to predict the functionality of different components in a similarly simulated environment or operating conditions using computational fluid dynamics (CFD).…”

“…He found that based on this flow field, PEMFC power density was 55.82% higher than that with parallel flow channels and 27.13% higher than that with single serpentine flow channels [12]. Lorenzini-Gutierrez et al proposed that the increase in the number of the flow field branches enables the improvement in the flow distribution uniformity and the reduction in the pressure drop between the inlet and outlet of flow channels [13]. Kang et al conducted experiments comparing the performance of the leaf flow channels based on the ginkgo and dicotyledonous leaf structures, the parallelstyle flow channels, and the serpentine-style flow channels [14].…”

As a critical component, the bipolar plate appreciably affects the performance of proton exchange membrane fuel cell (PEMFC). The flow field structure on the bipolar plate is significant in transporting the internal reaction gas and excess water. In the nature, the leaf veins provide efficient branch networks to the plant, contributing to distribute the nutrients in the whole system. By bionic means, a similar branching structure can be used to design flow channels on the bipolar plates for PEMFC, which helps distribute the reactant gas evenly and manage the water better. In this paper, a three-dimensional isothermal single phase model of the bio-inspired flow channel design based on the leaf vein pattern was presented. The effect of the angle between the main channel and sub-channels on the performance of PEMFC was studied at various cases. A PEMFC of 10.24cm2 activation area was assembled and examined experimentally. The results showed that increasing the angle appropriately was beneficial to improving the uniform oxygen distribution and excess water removal. After comprehensively analyzing the electrochemical performance, species distribution, and power loss of PEMFC, the optimal angle was presented.
