However, manufacturing of large-scale thin electrolyte remains a challenge. Wet powder spraying is an attractive technique to deposit <10 μm thin electrolyte when advanced atomizing techniques and optimized spraying process are integrated. Here ultrasonic atomization is integrated in the wet powder spray technique to reduce the thickness of electrolyte. Moreover, a parametric study is conducted to optimize the wet powder spray process to deposit uniform and crack-free electrolyte film. It is illustrated that tuning of solid loading rates and spray passes can affect the morphology of the as-sprayed electrolyte film, enabling the structural compactness of the sintered electrolyte layer. To maintain chemical stability of the electrolyte layer during sintering, effect of sintering temperature is further investigated to produce a physically thin, structurally dense, and chemically homogeneous electrolyte layer. The protonic ceramic electrochemical cells fabricated with optimized spraying and sintering parameters demonstrate excellent performance under both fuel cell and electrolysis modes.

This is directly due to the increase in reaction and mass transfer rates with temperature. Common sense suggests however that the increase of ionomeric material chemical degradation kinetics with temperature is likely to offset the above mentioned gain in performance and efficiency. In this computational study we investigate the combined effect of a high operating temperature, up to 120 °C, on the performance and stability of AEMFCs. Our modeling results demonstrate the expected positive impact of operating temperature on AEMFC performance. More interestingly, under certain conditions, AEMFC performance stability is surprisingly enhanced as temperature increases. While increasing cell temperature enhances degradation kinetics, it simultaneously improves water diffusivity through the membrane, resulting in higher hydration levels at the cathode. This, in turn, encourages a decrease in ionomer chemical degradation which depends on the hydration as well as on temperature, leading to a significant increase in AEMFC performance stability and, therefore, in its lifetime. These findings predict the possible advantage (and importance), in terms of performance and durability, of developing high-temperature AEMFCs for automotive and other applications.</p></div>","PeriodicalId":34318,"journal":{"name":"Journal of Power Sources Advances","volume":"11 ","pages":"Article 100066"},"PeriodicalIF":4.5,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.powera.2021.100066","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91665773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work focuses on the impact of catalyst loading, ionomer content and catalyst support on the performance of DIFCs. We achieve a performance rise from 95 mW cm<sup>-2</sup> to 219 mW cm<sup>-2</sup> under air operation by increasing the anode catalyst loading from 0.5 mg cm<sup>-2</sup> to 4 mg cm<sup>-2</sup>, which can be attributed to the increased abundance of active catalyst sites with higher loadings. In contrast, we find that the cathode loading for the oxygen reduction reaction (ORR) plays a minor role in the performance of DIFCs. Therefore, the cathode loading can be minimized to decrease the total amount of platinum-group metals and, consequently, to save cost. It was also found that an ionomer content of 30% on the anode side is optimal. Additionally, different carbon supports were investigated, where advanced high surface area carbon support showed superior performance to <span>Vulcan</span> with an increase of 20% in power density, motivating the development of new carbon supports for DIFCs.</p></div>","PeriodicalId":34318,"journal":{"name":"Journal of Power Sources Advances","volume":"10 ","pages":"Article 100064"},"PeriodicalIF":4.5,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.powera.2021.100064","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48461074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Until recently, immense attention was paid to designing and synthesizing advanced active materials for LIBs to enhance the battery characteristics. However, not the least crucial part of the battery, the current collector, was left unattended for a long time. Therefore, it is not surprising that the batteries reached their limits in power and energy densities, leaving the battery progress equal to an almost flat line. The only way to go ahead with the battery technology would be to design new architectures or to investigate new materials. Changing the battery current collector from planar to three-dimensional (3D) would offer dimensionality to the electrodes meaning short diffusion length for Li-ions, which will boost power density, more active material, and mechanical stability. Herein, in this review, various 3D architecture current collectors will be summarized, and recent advances in synthesis routes will be discussed to point out the importance of 3D structures. In addition, the correlation between the electrochemical performances of batteries and current collector architecture will be reviewed. More than 50 research publications related to the synthesis and performance of different 3D current collectors were reviewed and compared. The review results suggest that despite the outstanding performance, currently used technologies to obtain 3D current collectors make them unacceptable in the commercial sphere, and cheaper, faster and simple synthesis routes are desired to be explored.</p></div>","PeriodicalId":34318,"journal":{"name":"Journal of Power Sources Advances","volume":"10 ","pages":"Article 100065"},"PeriodicalIF":4.5,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.powera.2021.100065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46961550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
