During the NewSOC project, several of the improved concepts were integrated into commercial cells and stacks. The specific milestone was achieved by cells with a SolydEra half-cell, where UNISA deposited a thin CGO barrier layer through room temperature sputtering (down to 300 nm), developed in NewSOC, and a screen printed oxygen electrode. The cells were integrated into a SlydEra short stack together with state-of-the-art SolydEra standard cells as reference.
The NewSOC cells within the stack reached milestone M8:
- 25% improved ASR at 650 oC compared to SolydEra standard cells and
A low degradation rate <1%/1000 h in a 3000 h test
