“…Anode recirculation is generally used to allow for a high hydrogen stoechiometry without increasing hydrogen waste. Anode recirculation is implemented with a hydrogen mechanical pump, an ejector or an electrochemical pump, plus a gas-water separator [113]. Karnik et al [26] and Bao et al [19], calculate the ejector primary and secondary inlets from supply and return manifold pressures and temperatures.…”

“…Hydrogen circulation pumps and ejectors are the key components of hydrogen supply systems, and the schematic of different hydrogen supply subsystems is shown in Figure 4. Han et al [18] reviewed the hydrogen recirculation components of fuel cell vehicles, including mechanical pumps, ejectors and gas-water separators. To achieve small volume, low noise and low power consumption, a hydrogen circulating pump was presented, but has the operating difficulty (without lubricant) and high requirements for components such as seals and explosion-proof functions.…”

Review A Review of Fuel Cell System Technology: From Fuel Cell Stack to System Integration Weiqun Ren 1,*, Jun Shen 2, Xuebing Li 1, and Changqing Du 2 1 Dongfeng Commercial Vehicle Co. Ltd., 10 Dongfeng Avenue, Wuhan, China 2 Wuhan University of Technology, Wuhan, China * Correspondence: renweiqun@tsinghua.org.cn; Tel.: +86-139-1820-4209 Received: 14 October 2022 Accepted: 8 November 2022 Published: 18 December 2022 Abstract: The technology of hydrogen fuel cell vehicles (FCV) is the ultimate direction of clean energy vehicle development, and commercial vehicles are the most important application area for fuel cell commercialization. This paper summarizes the key components, technologies and development trends of the fuel cell stack, fuel cell system and vehicle integration at home and abroad, and points out that key materials (such as bipolar plates and membrane electrodes), key system components (such as air compressors and ejectors), high-power modular integration technologies, and fuel cell control technologies are the main factors influencing the commercialization of FCVs. Particularly, we put the main fouce on variable ejector or multi-stage ejector technology, integrated and optimized control technology, and multi-energy cooperative control technology due to their crucial roles in meeting the industrial development of FCVs in China. Furthermore, some guidance opinions are also provided for reference about the development and industrialization of FCVs.

In this study, a green hydrogen system was studied to provide electricity for an office building in the Sharjah emirate in the United Arab Emirates. Using a solar PV, a fuel cell, a diesel generator, and battery energy storage; a hybrid green hydrogen energy system was compared to a standard hybrid system (Solar PV, a diesel generator, and battery energy storage). The results show that both systems adequately provided the power needed for the load of the office building. The cost of the energy for both the basic and green hydrogen energy systems was 0.305 USD/kWh and 0.313 USD/kWh, respectively. The cost of the energy for both systems is very similar, even though the capital cost of the green hydrogen energy system was the highest value; however, the replacement and operational costs of the basic system were higher in comparison to the green hydrogen energy system. Moreover, the impact of the basic system in terms of the carbon footprint was more significant when compared with the green hydrogen system. The reduction in carbon dioxide was a 4.6 ratio when compared with the basic system.
