[交流] SOFC_审稿意见求助

各位虫友,

本人主要是做SOFC 阴极材料改性的,最近投了一篇nanoletters, 审稿人提到一个如下意见: Comment on the heat budget difference between reference and new process. This may be related to the cell stability.

因所投文章主要对比了普通阴极与浸渍改性后阴极的差异,实验结果表明浸渍后阴极极大的提高了电池性能并具有很好的稳定性。虽然对电池性能以及稳定性都有测试,但是实在是没有领会审稿人的这个意见。稳定性测试过程与热衡算无关啊。

请各位虫友帮咱分析下。谢谢!

牛人啊,SOFC做到nano letters很不赖。
是否能详细一点审稿人意见,上下文什么意思?以便方便理解

谢谢!

审稿人的具体意见如下: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

就是不太清楚第五个问题,用炉子加热,工作温度相同啊,热收支会有什么影响呢?

可能他认为是电池制备和测试过程中不同的应用温度导致不一样的测试结果。
不过,审稿人只是建议说明,并没有严格要求解释,不过不要留下把柄
