“…Scanning electron microscopy and transmission electron microscopy also showed the degradation of CLs and the increased agglomeration of Pt nanoparticles at higher pressures. Therefore, the structural design of CLs plays a decisive role in durability [152]. Mass transport can also be affected by damages to catalyst structures under high-gradient pressures; however, Kim et al [153] suggested that special pressure-resistant designs such as an inverse-opal-structured electrode (with a porous structure that can withstand high pressures and improve mass transfer and water management in CLs) can alleviate this issue.…”

Hydrogen is an ideal energy carrier in future applications due to clean byproducts and high efficiency. However, many challenges remain in the application of hydrogen, including hydrogen production, delivery, storage and conversion. In terms of hydrogen storage, two compression modes (mechanical and non-mechanical compressors) are generally used to increase volume density in which mechanical compressors with several classifications including reciprocating piston compressors, hydrogen diaphragm compressors and ionic liquid compressors produce significant noise and vibration and are expensive and inefficient. Alternatively, non-mechanical compressors are faced with issues involving large-volume requirements, slow reaction kinetics and the need for special thermal control systems, all of which limit large-scale development. As a result, modular, safe, inexpensive and efficient methods for hydrogen storage are urgently needed. And because electrochemical hydrogen compressors (EHCs) are modular, highly efficient and possess hydrogen purification functions with no moving parts, they are becoming increasingly prominent. Based on all of this and for the first time, this review will provide an overview of various hydrogen compression technologies and discuss corresponding structures, principles, advantages and limitations. This review will also comprehensively present the recent progress and existing issues of EHCs and future hydrogen compression techniques as well as corresponding containment membranes, catalysts, gas diffusion layers and flow fields. Furthermore, engineering perspectives are discussed to further enhance the performance of EHCs in terms of the thermal management, water management and the testing protocol of EHC stacks. Overall, the deeper understanding of potential relationships between performance and component design in EHCs as presented in this review can guide the future development of anticipated EHCs.

“…These parameters may affect the FCHEV driving range, reliability, economy, and durability [7]. Therefore, to eliminate the above-mentioned issue the FCHEV is mostly equipped with an ultra-capacitor or battery as an auxiliary energy storage system [8] - [9]. Such an arrangement of multiple energy sources increases the complexity of the power source unit of the vehicle and it requires an additional energy management methodology (EMM) to make the sources operate efficiently, reliable, and stable [10]- [11].…”

The plug-in fuel cell hybrid electric vehicle (PFCHEV) possesses the features of a battery EV and fuel cell hybrid electric vehicle (FCHEV). The PFCHEV provide a remarkably efficient driving range due to the integration of distinct energy sources. However, the range depends on the capacity of the energy sources, such as the battery and hydrogen storage tank. Considering the Indian geographical scenario, there is a lack of hydrogen refuelling stations and technology challenges. However, at present, in India, the technology development and installation of EV battery charging infrastructures enabled with fast charging are rapidly growing to make EVs feasible by solving a range anxiety issues. Therefore, in this paper, a novel battery charging methodology is proposed for PFCHEVs from the grid, DC fast charging station to achieve the desired range. This method may help to optimize the battery size and hydrogen fuel tank capacity without affecting the range of PFCHEVs.

A new real-time strategy is proposed in this article to optimize the hydrogen utilization of a fuel cell vehicle, by switching the control references of fueling regulators, based on load-following. The advantages of this strategy are discussed and compared, with advanced strategies that also use the aforementioned load-following mode regulator of fueling controllers, but in the entire loading range, respectively, with a benchmark strategy utilizing the static feed-forward control of fueling controllers. Additionally, the advantages of energy-storage function in a charge-sustained mode, such as a longer service life and reduced size due to the implementation of the proposed switching strategy, are presented for the dynamic profiles across the entire load range. The optimization function was designed to improve the fuel economy by adding to the total power of the fuel utilization efficiency (in a weighted way). The proposed optimization loop will seek the reference value to control the fueling regulator in real-time, which is not regulated by a load-following approach. The best switching threshold between the high and low loading scales were obtained using a sensitivity analysis carried out for both fixed and dynamic loads. The results obtained were promising—(1) the fuel economy was two-times higher than the advanced strategies mentioned above; and (2) the total fuel consumption was 13% lower than the static feed-forward strategy. This study opens new research directions for fuel cell vehicles, such as for obtaining the best fuel economy or estimating fuel consumption up to the first refueling station on the planned road.
