In this study, the utilization of Fe3O4-water nanofluid in PEM fuel cell cooling was investigated using a novel technique that considered all three of these features into account. The nanofluid was synthesized in varying mass ratios of 0.1%–0.5% and its thermophysical properties, EC, and zeta potential were measured. According to the findings, when EC and stability were taken into account, the pH value of the Fe3O4-water nanofluid should exceed 7. The thermal performance of the nanofluids was assessed using the performance evaluation ratio (PER), Mouromtseff number (Mo), and hr under both laminar and turbulent flow conditions.

Electromagnetic forming (EMF) is a high-speed, noncontact manufacturing technique that ensures uniform pressure distribution without lubricants and uses a single coil and power supply to produce BPP with intricate patterns, enabling the creation of complex, sharp-edged components with precision. This study investigates the impact of key parameters, such as discharging voltages (10 000, 11 000, and 12 000 V) and capacitor bank energy levels, using a 25 000 J EMF machine to fabricate copper-based BPP. Copper's high conductivity supports magnetic fields, Lorentz forces, and eddy currents, which are critical as electric currents flow through the workpiece during EMF. A novel EMF-based approach is also introduced to manufacture metallic BPP with superior quality and dimensional accuracy in flow field channels, offering significant advantages over traditional methods.

This study investigated the effects of perforation size and cell compression on the water transport in the cathode diffusion media of the structure-modified cell using x-ray radiography.

They are required to understand the fundamental thermal distribution mechanism and construct new cell configurations to relax thermal distribution effects. We performed a three-dimensional thermal distribution analysis coupled with computational fluid dynamics and chemical reactions in DIR-SOFCs with the three-cell stacking reactor model as a more practical model. As a result of the simulation for temperature distribution in each case of homogeneous and functionally graded paper structure catalysts (PSCs), we have found that the largest temperature drop occurs near the inlet in the bottom layer compared with the upper and middle layers in both cases and temperature distribution is milder in the functionally graded PSC. We also have found the importance of two-dimensional reaction rate controls in gas flow and cell staking directions to uniform temperature distribution of each layer.

In this paper, the cold-start performance of fuel cells with different initial water content of the membrane and starting modes was compared. Lowering the initial water content of the membrane could enhance the water storage capacity of the cell and improve the cold-starting performance of the cell, but infinitely low initial water content might cause the reverse polarity phenomenon, which would cause serious corrosion and degradation of the membrane electrode assembly (MEA). In constant voltage starting mode, reducing the starting voltage could increase the heat production of the cell, but it would weaken the water storage capacity of the cell. In the constant current starting process, lowering the starting current could improve the water storage capacity of the cell, which was beneficial to the cold start of the cell.
