“…Although there are numerous ways to humidify the cell but still bubble humidifier (passing the reactant gases through a hot water bath before they reach the inlet of the cell) is predominantly used for research purpose due its simple operation. Unlike in PEMFC humidification is required only to hydrate the membrane while in AEMFC humidification is necessary to hydrate the AEM and to provide adequate water for ORR at the cathode [154].Hence selecting a proper humidification strategy is a key to achieve desired performance in AEMFC. A part of water carried to cathode is being utilized in ORR, transported electro osmotically to anode and the excess water is removed through gas exhaust.…”

In spite of significant achievements in alkaline exchange membrane fuel cells (AEMFCs) in recent years, they are still lagging behind proton exchange membrane fuel cells (PEMFCs) due to performance instability. Among the relevant operational parameters of AEMFC, the researchers have found that poor water management within the cell was the main reason for failure of the system. In the past five years, numerous modeling and experimental works were reported proposing different strategies to improve water management of AEMFC. The achievable power output in AEMFCs is then comparable with that of PEMFCs or even more. Efforts have to be continued, but AEMFCs can become a strong competitor in the market place. This review paper discusses the strategies and developments impacting water management of AEMFCs providing knowledge source for upcoming studies.

“…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.

“…For example, for portable or vehicle applications, internal humidification may be preferable to reduce weight and space; while for stationary applications, sufficient humidification performance becomes more important, thus gas bubbling humidification or direct water injection method is more preferable. More details on FC humidification strategy can be found in the review paper [53].…”

Since the last two decades, microgrid, as one typical structure in smart grid framework, has been receiving increasing attention in the world. Meanwhile, fuel cell (FC), as one promising power source, has redrawn the attention of both academia and industry since the beginning of 21th century. Some encouraging achievements in FC technology have been realized thanks to the efforts taken in the last years. Due to this, it is seen that FC, as a clean and efficient energy source, is penetrating into different fields. Among the applications, integrating FCs into microgrids has shown interesting advantages on improving the performance of microgrids and promoting the use of the hydrogen energy. Some ongoing projects have shown that FCs of different power scales can be integrated into microgrids smartly and in different manners. Along with the advantages carried by the combination of the two technologies, many challenges lying on multiple domains are faced in the process. The challenges can be from the FC, the microgrid, and the integration of these two technologies. In this review paper, the advantages of integrating FCs into microgrids are summarized after recalling the knowledge background of FC. The challenges and ongoing researches on FCs and FCs based microgrids are then reviewed. Based on the analysis, the research directions are then extracted in view of the challenges.
