“…In the region dominated by the mass transport voltage drop, a plateau in the curve was observed for the amphiphilic functional group-modified C/Pt (Am@C/Pt-2, Am@C/Pt-3, and Am@C/Pt-4). This observation can be attributed to the reduced active species conduction resistance in the catalyst layer during the operation. , …”

“…This observation can be attributed to the reduced active species conduction resistance in the catalyst layer during the operation. 36,37 The proposed mechanism for active species conduction with Am@C/Pt-4 is presented in Figure 5. At the anode side (Figure 5a), H 2 is effectively fed into the Pt active area at the catalyst layer by the hydrophobic part (i.e., methyl group from the ODS molecule).…”

Carbon materials are widely utilized to support platinum (Pt) catalysts for proton exchange membrane fuel cells (PEMFCs). However, carbon surfaces generally promote hydrophobicity, which limits the transport of active species and lowers the efficiency of PEMFCs. Consequently, functional groups should be introduced on the carbon surface to create transport channels. One promising strategy is to modify the amphiphilic functional group on a carbon surface. In this study, the liquid-phase plasma process was applied to realizing a facile one-step synthesis of amphiphilic functional group-modified carbon-supported platinum (Am@C/Pt) to serve as a catalyst. This novel synthesis strategy provides several advantages over conventional processes, such as reducing the number of steps and minimizing the chemical and energy consumptions. Experimental results revealed that the PEMFCs' efficiency with Am@ C/Pt is mainly controlled by the number of hydrophilic and hydrophobic characters on the carbon surface. A single PEMFC demonstrated a maximum current and power density of 2.41 A cm −2 and 1.68 W cm −2 , respectively, at 0.7 V, which was significantly higher than those of commercially available carbon-supported Pt catalysts. Furthermore, Am@C/Pt demonstrated superior durability after 5000 test cycles.

“…Even if different forms of fuels are used, the chemical reactions are similar. The fundamental theory was proposed by Swiss scientist Christian Friedrich Schönbein in 1838, 55 and Sir William Robert Grove created the first fuel cell in 1839 56 . The theoretical voltage provided by the reaction of H 2 and O 2 is 1.23 V, but the voltage is less than this in practice.…”

Summary The transportation sector consumes a large amount of fossil fuels consequently exacerbating the global environmental and energy crisis. Fuel‐cell hybrid electric vehicles (FCHEVs) are promising alternatives in the continuous transition to clean energy. This article summarizes the recent advances pertaining to the optimization and cutting‐edge design of fuel‐cell hybrid electric vehicles, especially the fuel cell + battery hybrid topology, and discusses current technological bottlenecks hindering the commercialization of FCHEVs. The development of HEVs, markets, environmental and economic benefits, components, topologies, energy management strategies, degradation mechanisms, and safety standards of FCHEVs are reviewed. Proton exchange membrane fuel cells constitute the mainstream and most mature fuel cell technology for automobile applications. Battery hybridization is currently favored among the available FCHEV topological designs to improve the dynamic response and recover the braking energy. Energy management strategies encompassing logic rule‐based simple methods, intelligent control methods, global optimization strategies, and local optimization strategies are described, and issues and challenges encountering FCHEVs are discussed. In addition to promoting the construction of hydrogen supply facilities, future efforts are expected to focus on solving problems such as the high cost, durability of fuel cells, cold start, lifetime of batteries, security and comfort, system optimization, energy management systems, integration, and diagnosis of faults. This review serves as a reference and guide for future technological development and commercialization of FCHEVs.

Summary Studies into the effects of parameters used in the design of proton exchange membrane (PEM) fuel cell have been done. All the modelling parameters considered influenced the performance of the PEM fuel cells. The effect of the operating condition is shown to be significant. Increasing the operating temperature and operating pressure increases the mobility of ions and as a result the ionic conductivity is increased. In addition, the membrane is dried out when the correct humidity is not provided which increases membrane degradation. Adopting good design parameter is necessary for the efficient transportation of both reactants (fuel and oxygen). With regards to the use of flow plates, the serpentine flow plate is highly recommended. Material properties are very important in material selection and new product development. For the membrane electrode area (MEA); the membrane, the ionic conductivity is very important and should be given an important consideration. This investigation thoroughly examined operating condition, design parameters and material properties necessary for PEM fuel cells experiment. The investigation will further accelerate the commercialization of fuel cells and its integration in the automotive industry.
