Report on cell performance and durability test results (D5.2)
This deliverable D5.2 reports the electrochemical test results of the cells that have been manufactured in the project.
In total seven batches of more than 20 cell tests have been conducted, including initial performance characterization and long-term durability evaluation.
For testing, current-voltage curves (iV) and electrochemical impedance spectra (EIS) were measured for the initial characterization and cell voltages and EIS were recorded under current during durability tests.
The durability test condition was focused on 700 ᵒC with 10% H2 + 90% H2O supplied to the fuel electrode compartment and under current densities of -0.5 – -1 A/cm2 . Low degradation rates with <1%/1000 hours at -0.85A/cm2 were obtained on some of the selected cells tested for durability, which fulfilled the target of the project.
