“…Thanks to its advantages of low density, high porosity and controllable permeability, porous metal also has good heat dissipation performance, so it is very important for the uniform distribution of temperature and the discharge of water and heat from battery products. Mengshan Suo et al conducted a numerical study on the effect of the metal foam flow field on oxygen transport in PEM proton exchange membrane fuel cell under zero humidity by using a three-dimensional LBM model [20]. To focus on the hole.…”

In recent years, with the extensive use of fossil fuels, the global environment has deteriorated sharply, and human beings are facing the problem of energy conversion. Due to the high calorific value, light weight, abundant reserves, and pollution-free combustion of hydrogen energy, many countries hope to use hydrogen energy as a new sustainable energy instead of fossil energy. Through the introduction of proton exchange membrane fuel cells in class and literature research, it is found that proton exchange membrane fuel cell is a very representative energy technology with high efficiency, low noise, and cleanness in several new energy sources. Especially after the two goals of carbon neutralization and carbon peak are proposed, hydrogen energy has received high attention from basic research and industrial application. To further optimize the performance of proton exchange membrane fuel cells, this paper analyzes the flow field structure and energy management strategy of proton exchange membrane fuel cells for vehicles and makes a systematic summary on the basis of previous studies.

“…Among these advancements, the application of metal foam as a flow field in fuel cells has shown promising 2 potential [5,6]. Metal foams, characterized by their high surface area, interconnected porosity, and excellent thermal conductivity, present unique opportunities for enhancing mass transport [7], improving reactant distribution [8], and water management capability [9] within PEFCs. The incorporation of metal foam as a flow field introduces several advantages over conventional flow field designs.…”

This paper presents a comprehensive evaluation of metal foam employment within polymer electrolyte fuel cells (PEFCs) and compares it with conventional serpentine channels from both experiment viewpoints and computational fluid dynamics simulation. The experiments are designed to study the effects of material, area density, compression ratio, and final thickness of metal foam. Additionally, the influence of housing plate material and relative humidity (RH) is also tested for the first time. The results reveal that at RH=75-100%, the best distributor design is nickel foam with a compression ratio of 70%, a final thickness of 0.5mm, and SS-304 housing plate, which delivers 3110 mA cm-2 as limiting current density that is scarce in the literature. The PEFC with this foam distributor shows a 10% improvement in maximum power density and 45% in limiting current density compared to the serpentine channel case. While at RH=30%, the same foam flow field with a final thickness of 1mm is a superior option. The experiments also indicate that maximum power density increases by 23% as the compression ratio rises from 0 to 70%, while reducing final thickness from 1 to 0.5 mm causes a 19% enhancement in cell performance. Simulation results reveal that metal foam is more successful in evenly reactant distribution so that the average oxygen mass fraction at the cathode catalyst layer is increased by 38% in the metal foam case compared to the serpentine channel.

“…Some scholars have designed some special structures to improve the water and heat distribution in the cathode flow field, such as the parallel flow field with hydrophilic needles, 23 dot matrix and sloping baffle flow field, 24 multi-plates structure and integrated structure channel, 25 and 3D fine mesh structure. 26,27 Metal foam flow field [28][29][30][31] is also a relatively common flow field in recent international research, which can provide a more uniform current density distribution, but the production cost of this flow field is relatively high, which limits its further development to a certain extent. In addition, bionic flow fields have also become one of the research hotspots in recent years.…”

Summary The performance and durability of the proton exchange membrane fuel cells (PEMFCs) are highly influenced by the transport of reactants and water distribution in the cathode flow field. In this study, a novel staggered structure is proposed for the cathode flow field, and the effects of flow field geometric parameters on the transport and distribution characteristics of water and oxygen in the fuel cell are studied by numerical simulation. Two parameters are considered, namely the size of the hole (W) and the number of segments in which the channel is divided equally (L). The simulation results show that compared with the traditional parallel flow field, when W = 0.5 mm, the current density of PEMFC has increased by 11.9%, and the uniformity of oxygen and water concentration distribution inside the fuel cell has been significantly improved. In addition, when W = 0.5 mm and L = 5.56 mm, the fuel cell shows the best performance with 15.8% increase in power density. In this case, the fuel cell shows a more uniform current density distribution. Meanwhile, the staggered flow field reduces the maximum water saturation by 42.5% and without increasing the total pressure drop vs the conventional parallel flow field. Highlights The staggered flow field (SFF) is proposed to improve species concentration distribution. The power density of PEMFC with SFF has increased by 15.8%. The drainage performance of SFF is significantly improved, maximum water saturation of PEMFC is reduced by 42.5%. This new structure does not increase the pressure drop of the cathode channel.
