“…This is another modification of serpentine channel which is not tried earlier. The study that closely aligns with our research entails a configuration featuring multiple openings and exits interconnected by parallel channels (Hamrang et al, 2023). In their investigation, the authors conducted a numerical comparison between a parallel serpentine flow field and a baffled serpentine flow field, identifying potential enhancements.…”

The paper presents an analysis of the performance of a Proton Exchange Membrane (PEM) fuel cell, which is equipped with a flow field design featuring dual inlets and outlets, while operating under conditions of excess stoichiometry. These experiments were conducted using a fuel cell system connected to a station that allowed for the precise adjustment of gas flow rates. During the initial phase of experimentation, various proportions of excess oxygen were systematically applied, while maintaining constant hydrogen flow rates of 80 mL/min and 100 mL/min. Particularly noteworthy, for the case of a 100 mL/min hydrogen gas flow rate and the optimized excess oxygen proportion of 150%, further experiments were undertaken to ascertain the ideal humidification conditions. The outcomes of these experiments revealed that a hydrogen gas flow rate of 100 mL/min consistently outperformed the 80 mL/min flow rate in terms of fuel cell performance. Moreover, it was observed that the introduction of excess oxygen significantly improved performance, up to a 50% oxygen proportion for the 80 mL/min hydrogen flow rate and up to a 150% proportion for the 100 mL/min hydrogen flow rate. One intriguing observation pertained to the influence of humidification. Specifically, it was found that the utilization of a humidification temperature of 100°C, or the absence of humidification altogether, resulted in notably diminished power output. In contrast, intermediate humidification temperatures of 60°C, 70°C, 80°C, and 90°C consistently yielded identical maximum power points (MPP) when combined with a 150% excess oxygen supply and a hydrogen flow rate of 100 mL/min. The twin inlet-twin outlet flow field provides a slight advantage over the conventional serpentine flow field in the overall analysis.

“…Many studies have also carried out the optimal design of cross-section aspect ratio [126][127][128] to improve the performance of fuel cells. Through mathematical modeling and statistical analysis, Zhang et al [126] discussed the influence of length, width, and depth on the PEMFC performance of the serpentine flow field and obtained the optimal aspect ratio design in several flow channels, as shown in Figure 31.…”

The performance of a polymer electrolyte membrane fuel cell (PEMFC) closely depends on internal reactant diffusion and liquid water removal. As one of the key components of PEMFCs, bipolar plates (BPs) provide paths for reactant diffusion and product transport. Therefore, to achieve high fuel cell performance, one key issue is designing BPs with a reasonable flow field. This paper provides a comprehensive review of various modifications of the conventional parallel flow field, interdigitated flow field, and serpentine flow field to improve fuel cells’ overall performance. The main focuses for modifications of conventional flow fields are flow field shape, length, aspect ratio, baffle, trap, auxiliary inlet, and channels, as well as channel numbers. These modifications can partly enhance reactant diffusion and product transport while maintaining an acceptable flow pressure drop. This review also covers the detailed structural description of the newly developed flow fields, including the 3D flow field, metal flow field, and bionic flow field. Moreover, the effects of these flow field designs on the internal physical quantity transport and distribution, as well as the fuel cells’ overall performance, are investigated. This review describes state-of-the-art flow field design, identifies the key research gaps, and provides references and guidance for the design of high-performance flow fields for PEMFCs in the future.

Due to factors including low emission values, great energy efficiency, and reduced environmental contamination, fuel cells have gained popularity recently. Fuel cells using polymer electrolyte membranes can distribute reactant gases through gas flow channels and remove water that forms during the reaction from the fuel cell. This study looked at how different channel sizes and channel cross-section geometries (rectangular, triangular, and semicircular) affected the distribution of current density, oxygen concentration, velocity, and temperature parameters on the cathode catalyst in the flow channels of a single-channel PEM fuel cell at 0.75 V cell voltage. The model with the highest current density and consequently the best fuel cell performance was determined to be 9 x 10-5 A/cm2 in a channel with a height and breadth of 0.1 cm and A = 1 cm2, according to the data obtained. The flow channel length was assessed at 0.2 in the analysis results for all models because it did not alter with the oxygen concentration distribution. In varied channel designs with the same area, it has been found that the velocity distribution varies inversely with the current density. The maximum velocity value recorded at this location was 33.1 m/s in a semicircular canal with a R of 0.34 mm. It has been discovered that fuel cells from more places operate better as a result.
