NewSOC, supplementary information to WT2.5.4 "Cells with honeycomb structured oxygen electrodes": electrochemical and post-mortem data sets.

These are data set, related to participation of the IEN in project NewSOC. It includes results of the SEM-EDS analysis of the cells with hexagonal current collecting net and electrochemical performance data, both EIS and C-V characteristics. Results are grouped in zip archives, named according to cell design, “infill-net”.

Compositions:

LNF – LaNi_0.6Fe_0.4O₃ (net)

LSC – La_0.6Sr_0.4CoO_3-d (infill)

LSF – La_0.5Sr_0.5FeO_3-d (infill)

LSCCF – La_0.6Sr_0.4Co_0.15Cu_0.05Fe_0.8O_3-d (net)

PCM – Pr_0.5Ca_0.5MnO₃ (net)

BSCFM – Ba_0.5Sr_0.5Co_0.725Fe_0.2Mo_0.075O_3-d (infill)

Data presentation.

C-V characteristics:

This is text files, generated by Zahner galvanostat, with self-decriptional titles.

“05iv_650c_100h2+100h2o_500air.txt” –  measurement at 650°C, 100 mL/min H₂ and 100 mL/min H₂O on fuel side, 500 mL/min of air on air side.

EIS data:

EIS results were extracted from proprietary binary files, generated by Zahner galvanostat, and raw data is generally meaningless except the owners of such hardware. So, extracted EIS can be found in Excel files, used in analysis, in sheet “Experimental”. Other sheets in xlsx include some metadata (“info”), results of the equivalent circuit fit (“fit”) and some plots. Fit results might not be relevant.  

SEM

Post-mortem results presented as SEM images (tif or jpg files) and pdf files with results of the EDS analysis.
