“…In addition, our team also found that the proper increase for the curvature of the flow channel can also improve the performance [32]. Zhengkai Tu et al have also been conducted on the flow channel design and water heat transfer of air-cooled fuel cells by some experimental and simulation studies [33][34][35][36][37][38], they found that series configuration provides higher power output at the expense of lower fuel utilization in comparison with parallel configuration. They also studied the effect of ultra-thin steel bipolar plates on fuel cell performance.…”

Due to growing energy and environmental issues, clean energy technology has gained recognition around the world. Because of its great energy transfer efficiency, outstanding power density, low operational temperatures, and environmental protection, PEMFC has been employed extensively in a variety of fields. But the thermal management of PEMFC has been a great challenge limiting its commercialization. Ineffective heat management strategies can shorten the fuel cell battery's lifespan in addition to affecting its performance. Therefore, this study provides an overview of how fuel cell bipolar plate structure and thermal management techniques have improved fuel cell performance. The results show that the tree-shaped fractal fuel cell bipolar plate, novel tapered dual serpentine channel and so on can enhance the heat dissipation effect of the bipolar plate and the temperature uniformity of the MEA, and form a uniform temperature distribution and pressure. Process strategies such as the new thermal management system with a thermal peak regulator can efficiently regulate the peak temperature and the average temperature of the fuel cell system to improve its starting performance. Most importantly, this research can help to alleviate the energy tension and reduce the environmental pressure.

“…It has the advantages of high electrical conductivity and corrosion resistance, but it also has problems such as difficult processing and poor mechanical properties [ 13 , 14 , 15 , 16 ]. Metal bipolar plates have excellent mechanical properties, processing properties, and electrical conductivity [ 17 , 18 , 19 , 20 , 21 ]. However, because of the poor corrosion resistance of metal BPs compared to graphite BPs, methods such as corrosion-resistant coatings are needed to overcome the degradation of fuel cell durability due to corrosion resistance [ 7 , 22 , 23 , 24 ].…”

Composite bipolar plates (BPs) hinder their application in proton exchange membrane fuel cells (PEMFC) because of their poor conductivity and mechanical properties. Nanofillers can effectively solve this problem but often have a limited effect due to their easy agglomeration. In this work, a continuous mesh carboxylated multi-walled carbon nanotube (MWCNT) coating on the surface of graphite was synthesized by chemical vapor deposition (CVD) and carboxylation modification, and the composite BPs were prepared by molding using prepared reticulated carboxylated MWCNTs, expanded graphite, and resin. By optimizing the carboxylation treatment time and the content of the nano-filler, the composite BPs had the best performance at a 15 min carboxylation treatment time and 2.4% filler content. The planar conductivity reached up to 243.52 S/cm, while the flexural strength increased to 61.9 MPa. The thermal conductivity and hydrophobicity were improved compared with the conventional graphite/resin composite BPs, and good corrosion resistance has been demonstrated under the PEMFC operating environment. This work provides a novel nanofiller modification paradigm for PBs.
