This paper opens the doors to the enhancement of SOFC performance through traps-designed interconnects, aimed at enhancing mass transfer and electrochemical conversion efficiency. A numerical investigation is conducted to analyze the effects of traps, including their number and three-dimensional size (length, width, and height), on SOFC behavior. Results show that the traps design effectively addresses the widely reported issue of poor reactants’ distribution in the under-rib areas. Additionally, increasing traps’ size enhances SOFC performance, with traps length identified as the primary contributor to improvement. However, variations in traps width exhibited inconsistencies in its impact. As a result, these parameters were carefully optimized for the optimal performance. The optimal configuration for a three-traps design is determined to be 12 mm in length, 0.3 mm in width, and 1 mm in height, resulting in a 14% increase in power output compared to conventional design. A thermo-mechanical analysis is also conducted, revealing that the electrical performance comes as a compromise with the mechanical stability of the cell. Specifically, an increase in thermal stresses around traps corners is observed, resulting in a significant rise in the probability of electrolyte failure probability. The authors suggest incorporating support layers or further optimizing trap shapes with mechanical stresses as a study constraint to enhance SOFC durability in response to these findings.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 5","pages":"1907 - 1927"},"PeriodicalIF":2.6,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Potential control can be used to toggle the H_ads coverage to enable multicycle Pt deposition. Specifically, the applied potential is stepped between + 0.4 V_SSCE and − 0.8 V_SSCE, transiting the regime of overpotential activated Pt electrodeposition. The amount of metal deposited depends on capacitive charging delays associated with the double layer and competitive Cl⁻, H, and PtCl_4-x(H₂O)_x^−2+x adsorption. In addition, significant potential deviations arise from ohmic losses that are a function of the supporting electrolyte, cell geometry, and PtCl_4-x(H₂O)_x^−2+x concentration. Taken in combination, the delay in reaching the growth termination potential leads to additional metal deposition and roughening per pulse cycle. Experiments with a parallel plate cell enable the resistive component of the ohmic losses to be specified by the separation between the working and reference electrodes. During multicycle deposition, the H_upd pseudo-capacitance associated with Pt surface sites leads to further RC time constant delays and roughening. The transition to three-dimensional growth leads to low-density films as clearly evidenced after 50 deposition cycles. The difficulties with the pulsed potential scheme can be circumvented, or at least minimized, by using electrolyte exchange to introduce the PtCl_4-x(H₂O)_x^−2+x reactant at a fixed potential, i.e., − 0.8 V_SSCE into the weakly acidic electrolyte. The resulting fractional Pt coverage per cycle is a monotonic function of K₂PtCl₄ concentration and ranged from 0.2 to almost a complete monolayer reflecting the competition between PtCl_4-x(H₂O)_x^−2+x reduction and adsorption of the blocking H_ads layer.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 4","pages":"1401 - 1421"},"PeriodicalIF":2.6,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study optimized the fabrication parameters of LIG electrodes on the thinnest commercial polyimide tapes by employing response surface methodology (RSM) combined with a randomized Box-Behnken experimental design (BBD). Kapton polyimide (PI) tapes were laser-engraved to create a three-electrode electrochemical system. Laser power, engraving speed, and laser distance were evaluated using the heterogeneous kinetic constant (<i>k</i>°) as the response variable. Optimal conditions were identified as 1.925 W power, 2729 mm/min speed, and 7.6 mm focal distance, yielding peak differences of 93 mV, electric double-layer capacitance of 1.95 µF, anodic peak current of 60.1 µA, and <i>k</i>° of 0.0074 cm/s. Raman spectroscopy of the LIG showed peaks at ~ 1350 cm⁻¹ (D band), ~ 1580 cm⁻¹ (G band), and ~ 2700 cm⁻¹ (2D band), indicating disordered and ordered graphitic structures. XRD analysis confirmed the presence of amorphous adhesive material and partial restoration of the graphene structure, with peaks corresponding to reduced graphene oxide (rGO) and graphitic planes.

CC determination yielded a linear range of 2 to 400 µM with a limit of detection (LOD) of 0.37 µM and a limit of quantification (LOQ) of 1.25 µM.

In this study, the ion conductivity and Na metal stability of the Na-rich anti-perovskite Na₃OCl were investigated. Na₃OCl was prepared by controlling the Cl⁻/O²⁻ ratio. Dense pellets of Na₃OCl were prepared by sintering. The conductivities of stoichiometric and Cl-excess Na₃OCl are 9.7 × 10⁻⁶ and 3.0 × 10⁻⁵ S/cm at 240 °C, respectively. The Na⁺ vacancies, which were introduced as the charge compensation of Cl⁻/O²⁻ substitution, are considered to be the origin of the conductivity improvement. Off-stoichiometry of Cl⁻/O²⁻ can also be effective when Na₃OCl is used as the anode composite. The decomposition of Na₃OCl at the Na metal interphase was suggested, indicating that Na₃OCl is unstable with Na. These results contradict the current knowledge on the charge–discharge performance of Na₃OCl anode composites. The present results indicate that the Na⁺ conduction properties and stability in Na₃OCl with high crystallinity are different from the in situ-formed Na₃OCl in previously reported anode composites.
