“…The grid independent test was performed to ensure that the meshing element utilised was the optimum meshing, since a greater number of meshing elements increases simulation time, but a lesser number of meshing elements or inadequate meshing results in an inaccurate simulation result [27]. As indicated in the Figure 1 below, the ideal meshing size for analysis is 1177714 mesh elements for a distributor and 1002308 mesh elements for a serpentine cooling plate.…”

“…It was also known that the pumping power value increased as the Reynolds number was increased. The inclusion of nanoparticles has resulted in increased internal friction and flow resistance, which eventually raises the necessary pumping power [27]. The improvement was intended to allow more viscous nanofluids to circulate through the cooling system.…”

Proton Exchange Membrane Fuel Cell (PEMFC) is a renewable technology application for vehicle power sources that is a viable challenger for a safe and efficient power generation. Nanofluids adoption is one of the advancements in PEMFC heat management. In addition to that, Bio Glycol is also introduced as a non-toxic, renewable fluid with 30% lower viscosity than regular petroleum-derived propylene glycol at low temperatures. The 0.5% volume concentration of hybrid nanofluids of Aluminium Oxide (Al2O3) and Silicon Dioxide (SiO2) in water:BG at 60:40 volume ratio was investigated in this work. This paper investigated the heat transfer improvement and the pumping power effect in mini channel of PEMFC distributor and serpentine cooling plate with the adoption of hybrid Al2O3 and SiO2 nanoparticles in water: Bio Glycol (BG). The simulation conducted using ANSYS Fluent, under laminar region of 300 to 1800 and constant heat flux of 6500 (W/m2) to imitate the heat generation in a PEMFC bipolar plate. The : ratios used were 10:90, 30:70, 50:50, and 70:30. The findings suggested that : (30:70) in water: BG provides the highest improvement of 14.4% in the serpentine cooling plate and 20.9% in the distributor cooling plate at Re 1800. However, the pressure drop for both plates was increased up to 7 times greater than the base fluid. The advantage ratio was then calculated to assess the feasibility of nanofluids in PEMFC cooling plates. As a conclusion it was recommended that the serpentine cooling plate outperforms the distributor cooling plate in terms of both heat transfer and pumping power need

Efficient thermal management is essential for the optimal performance and durability of the Proton Exchange Membrane Fuel Cell (PEMFC). However, the conventional passive cooling methods require a larger heat exchanger for better heat dissipation. Alternatively, nanofluids as a coolant have gained attention recently due to their enhanced heat transfer properties. This investigation aims to evaluate the thermal performance of hybrid nanofluids in a distributor type of PEMFC cooling plate. In this investigation, 0.5% volume concentration of mono Al2O3, mono SiO2 nanofluids, and hybrid Al2O3:SiO2 nanofluids with a mixture ratio of 10:90, 30:70, 50:50, and 70:30 in 60:40 W:EG were investigated. The cooling plate was modelled and a fixed heat flux of 6500 w/m2 was applied to replicate the actual working parameter of PEMFC. The study shows that the heat transfer coefficient was improved by 61% in 10:90 hybrid nanofluids of Al2O3:SiO2 in W:EG in comparison to the base fluid. Meanwhile, the accompanied pressure drops in 10:90 hybrid nanofluids of Al2O3:SiO2 in W:EG show a reduction up to 4.38 times lower as compared to single Al2O3 nanofluids at Re 1800. This is advantageous since it will reduce the parasitic loss related to the PEM fuel cell.
