“…A study [47] reported that AEMFCs exhibit improved performance and high stability in 2018. In 2019, numerous reviews of PEMFCs were published, including a review of PEMFC-based micro-combined heat and power systems [48], PEMFC applications for electric vehicles and energy management strategies [49,50], PEMFC poisoning by contaminants and impurities [51], mechanical compression effects and stress effects on PEMFCs [52,53], humidification strategy for PEMFCs [54], and design optimization for PEMFCs [55]. These reviews are similar to the 2000 reviews of SOFCs.…”

Renewable and sustainable energy technologies must undergo commercialization before contributing to people's sustainable development. Among different approaches, commercialization to become unicorn start-ups has attracted considerable attention. Unicorn start-ups are companies achieving a valuation of over US$1 billion before launching initial public offerings. Herein, a company adopting solid oxide fuel cells as its single product and becoming a unicorn start-up is considered the case company (Company B). Established in 2001, Company B accumulated US$825.7 million of actual funding and a peak valuation of US$2.9 billion before being publicly listed. After being listed in July 2018, Company B achieved unicorn start-up status. Searching ScienceDirect Online and the IEEE/IET Electronic Library, this. study collects reviews of fuel cell technology development trends. From CB insights, the study collects the timing and amount of funding received by fuel cell-related unicorn start-ups worldwide. The Derwent Innovation (DI) tool is employed to analyze the status of fuel cell-related patent applications of these unicorn start-ups. This study integrates technology review, business status, and patent application data for analysis. Unlike previous technology reviews focusing on researches and developments, this study emphasizes the analysis of intellectual-property-based (IP-based) commercialization strategies. Specifically, it analyzes key factors explaining how a company producing solid oxide fuel cells could transform into a unicorn start-up. These factors are compiled into a ladder framework to provide a reference. Five quantitative indices are promoted. From the managerial point of view, this framework provides an executable guideline for effectively transforming sustainable energy technology into a high-valuation unicorn start-up.

“…The SOH of PEMFC and battery are traced online by an adaptive filter and the results show that without SOH estimation, the charge sustenance objective of battery cannot be achieved when the power sources go under degradation. A review of health-conscious EMSs for FCHEVs is presented in [33] and it has been concluded that accurate degradation estimation should be integrated into the existing EMSs to enhance the durability of the system.…”

Investigating the impact of ageing and thermal management of a fuel cell system on energy management strategies

et al. 2020

This paper studies the impact of two significant aspects, namely fuel cell (FC) degradation and thermal management, over the performance of an optimal and a rule-based energy management strategy (EMS) in a fuel cell hybrid electric vehicle (FCHEV). To do so, firstly, a vehicle model is developed in simulation environment for a low-speed FCHEV composed of a FC stack and a battery pack. Subsequently, deterministic dynamic programming (DP), as an optimal strategy, and bounded load following strategy (BLFS), as a common rule-based strategy, are utilized to minimize the hydrogen consumption while respecting the operating constraints of the power sources. The performance of the EMSs is assessed in different scenarios. The first objective is to clarify the effect of FC stack degradation on the performance of the vehicle. In this regard, each EMS determines the required current from the FC stack for two FCs with different levels of degradation. The second objective is to evaluate the thermal management contribution in improving the performance for the new FC compared to the considered cases in scenario one. In this respect, each strategy deals with determining two control variables (FC current and cooling fan duty cycle). The results of this study indicate that negligence of adapting to the PEMFC health state, as the PEMFC gets aged, can increase the hydrogen consumption up to 24.8% in DP and 12.1% in BLFS. Moreover, the integration of temperature dimension into the EMS can diminish the hydrogen consumption by 4.1% and 5.3% in DP and BLFS respectively.

“…With the environmental deterioration and energy crisis, developing green energy and new energy vehicles has become the consensus of government and public [1][2][3]. Compared with the small-power new energy vehicles like the plug-in hybrid vehicles and hybrid electric vehicles, the hybrid light rail vehicles are more suitable for urban public transportation, due to its high-power level and large-capacity.…”

A Firefly Algorithm Optimization-Based Equivalent Consumption Minimization Strategy for Fuel Cell Hybrid Light Rail Vehicle

et al. 2019

View full text Add to dashboard Cite

To coordinate multiple power sources properly, this paper presents an optimal control strategy for a fuel cell/battery/supercapacitor light rail vehicle. The proposed strategy, which uses the firefly algorithm to optimize the equivalent consumption minimization strategy, improves the drawback that the conventional equivalent consumption minimization strategy takes insufficient account of the global performance for the vehicle. Moreover, the strategy considers the difference between the two sets of optimized variables. The optimization objective is to minimize the daily operating cost of the vehicle, which includes the total fuel consumption, initial investment, and cycling costs of power sources. The selected case study is a 100% low-floor light rail vehicle. The advantages of the proposed strategy are investigated by comparison with the operating mode control, firefly algorithm-based operating mode control, and equivalent consumption minimization strategy. In contrast to other methods, the proposed strategy shows cost reductions of up to 39.62% (from operating mode control), 18.28% (from firefly algorithm-based operating mode control), and 13.81% (from equivalent consumption minimization strategy). In addition, the proposed strategy can reduce fuel consumption and increase the efficiency of the fuel cell system.
