SOFC_審稿意見(jiàn)求助
|
|
各位蟲友, 本人主要是做SOFC 陰極材料改性的,最近投了一篇nanoletters, 審稿人提到一個(gè)如下意見(jiàn): Comment on the heat budget difference between reference and new process. This may be related to the cell stability. 因所投文章主要對(duì)比了普通陰極與浸漬改性后陰極的差異,實(shí)驗(yàn)結(jié)果表明浸漬后陰極極大的提高了電池性能并具有很好的穩(wěn)定性。雖然對(duì)電池性能以及穩(wěn)定性都有測(cè)試,但是實(shí)在是沒(méi)有領(lǐng)會(huì)審稿人的這個(gè)意見(jiàn)。穩(wěn)定性測(cè)試過(guò)程與熱衡算無(wú)關(guān)啊。 請(qǐng)各位蟲友幫咱分析下。謝謝! |

謝謝! 審稿人的具體意見(jiàn)如下:In this article, the authors present progress in improving interface properties via multistep sintering of nanometer sized electrolyte and cathode materials. The enhanced oxygen exchange rate is verified in both measured impedance and electrochemical performance. The power density is significantly higher using the reported fabrication process, achieving > 1 W/cm^2 at 700 deg C. This article can be a good fit to Nano Letter if the following questions are answered: 1. Can the authors extrapolate the exchange current densities (j0) using Tafel equation, and compare the activation energy of the exchange current densities of the reference and new process? Would the enhanced j0 be proportional to the TPB or surface area change? 2. Any available data on surface area, such as BET or mercury intrusion? Any before and after surface area comparison other than SEM? This can be a good complimentary data to the SEM microstructure analysis 3. Any evidence to the enhanced performance is mainly due to (narrow down the main cause) a. surface area enhancement b. higher TPB densities (similar to a) c. improved particle-to-particle contact d. lowering onset temperature of Mn4+ to Mn3+ e. combination of above 4. The performance is very stable at high temperature and high current density. Any speculation why this would be the case? It’s generally speculated that higher surface area will cause faster degradation in performance 5. Comment on the heat budget difference between reference and new process. This may be related to the cell stability 就是不太清楚第五個(gè)問(wèn)題,用爐子加熱,工作溫度相同啊,熱收支會(huì)有什么影響呢? |

可能他認(rèn)為是電池制備和測(cè)試過(guò)程中不同的應(yīng)用溫度導(dǎo)致不一樣的測(cè)試結(jié)果。 不過(guò),審稿人只是建議說(shuō)明,并沒(méi)有嚴(yán)格要求解釋,不過(guò)不要留下把柄 [ 發(fā)自手機(jī)版 http://www.gaoyang168.com/3g ] |
