The three-dimensional and multi-phase models are established by using the simulation software package (ANSYS FLUENT). The findings demonstrate that the battery's output performance reaches its peak when the baffle angle is set at 45°. When the output current density is 0.7 A/cm², the power density of the 45° baffle increases by 18.87%. The pressure loss is not only lower than that of the 60° baffle but also exhibits no significant difference when compared to the 30° baffle.

The topology of the parallel dual-boost DC/DC converter system for the EIS measurement is presented. The DC_dc and DC_ac modules in the converter system implement the DC current and the sinusoidal EIS perturbation current independently. Simulation results show that the proposed perturbation current generation method can be implemented efficiently. In the frequency domain, the current of DC_dc couples to the perturbation current of DC_ac, leading to a reduction in the accuracy of the current amplitude after superposition. The mechanism of current amplitude reduction after superposition is discussed. Feed-forward compensation and fuzzy compensation optimization are proposed for the DC_dc current control. Both compensation algorithms achieve excellent results. A comprehensive framework for evaluating the compensation effect is presented. The evaluation results show that feed-forward compensation has a better advantage in solving the above problems due to its simplicity and less impact on hardware control. Experimental results show that with the optimization algorithm, the input perturbation current increases from 6% to 83% of the theoretical value.</p>","PeriodicalId":12566,"journal":{"name":"Fuel Cells","volume":"24 1","pages":"17-31"},"PeriodicalIF":2.8,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139865851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When a paper-structured catalyst (PSC) with a dispersion of Ni-loaded flowerlike Ce_0.5Zr_0.5O₂ (Ni/CZ(F)) was applied to the anode of an electrolyte-supported cell (ESC), the open-circuit voltage of the cell directly fed simulated biogas was increased from 0.87 to 0.98 V at 750°C. The rates of cell-voltage degradation and coke formation of the ESC with the Ni/CZ(F)-PSC during 100 h of operation were 4.3% kh⁻¹ and 0.43 mg-C g-PSC⁻¹ h⁻¹, respectively, which were lower than those of an ESC with a Ni-loaded PSC without the CZ(F) dispersion (10.4% kh⁻¹ and 8.1 mg-C g-PSC⁻¹ h⁻¹, respectively). This performance improvement is attributed to the unique porous morphology and high oxygen storage capacity of CZ(F), which can contribute to the prevention of Ni agglomeration and the removal of coke from the catalyst surface, respectively.

Indeed, it has been confirmed that hydrogen, already identified as a key element by the President of the European Commission Ursula von der Leyen at the European Hydrogen Week 2021, is one of the main pillars of the “RePowerEU” plan intending to save energy, produce clean energy, and diversify energy supplies in the context of the war in the Ukraine. This plan will involve a large number of technologies for hydrogen production, storage and transport, at various scales and for different applications (for more information see also: https://commission.europa.eu/strategy-and-policy/priorities-2019-2024/european-green-deal/repowereu-affordable-secure-and-sustainable-energy-europe_en).&lt;/p&gt;&lt;p&gt;Solid Oxide Electrolysis technology can play a key role for a cost-competitive clean hydrogen production thanks to its high efficiency. It can also contribute to the generation of synthetic fuels or molecules of interest, with the specific asset of steam and CO&lt;sub&gt;2&lt;/sub&gt; co-electrolysis to produce syngas (composed of H&lt;sub&gt;2&lt;/sub&gt; and CO). In addition to their high efficiency, Solid Oxide Fuel Cells (SOFCs) are also characterized by a large fuel flexibility, including non-carbon based liquid fuels like ammonia, which can also contribute to limit the CO&lt;sub&gt;2&lt;/sub&gt; emissions of several sectors. Finally, reversible systems can be considered combining electrolysis and fuel cell modes, which are particularly relevant when using intermittent renewable energy sources.&lt;/p&gt;&lt;p&gt;Thanks to decades of research efforts from materials up to the complete system, SOFC and SOE technologies have gained in maturity. It was reflected by the conference, gathering 253 communications, respectively 117 oral and 136 poster presentations, in a well-balanced program covering technology development and scientific achievements, from fundamental research to the latest achievements in terms of demonstrations (www.efcf.com).&lt;/p&gt;&lt;p&gt;On one hand, sessions were devoted to the technology status at industry, the system design or the stack performances and lifetime, while on the other hand, sessions were dedicated to the cell and material developments, with the support of modeling and advanced characterization.
