abstract = {The interaction between Sandvik's coated Sanergy HT 441 (EN
1.4509) with a cerium‐cobalt layer as chromium evaporation
barrier and a glass‐ceramic composite sealant on the basis
of BaO‐CaO‐SiO2 was investigated in this study. The
oxidation behavior of the steel was analyzed by long‐term
weight change measurements of strip samples at 800 °C for
10,000 h followed by scanning electron microscopy on
cross‐sectioned samples. A double oxide layer was formed
consisting of chromia close to the steel and a layer with
$18 wt.\%$ Cr, $11\%$ Co, $10\%$ Mn to the air side. The
interface of the joined samples had a reaction layer similar
to the oxidized steel surface with an additional phase
formation consisting of Co/Mn/Fe and low in oxygen facing
the glass‐ceramic interface. After these preliminary tests
the coated Sanergy HT 441 was integrated as frames into a
four layered F10‐stack with 80 cm2 cell area and was
tested for 3,500 h at operation temperature of 700 °C and
0.5 A cm−2 constant current mode followed by 20 thermal
cycles between 700 and 200 °C. The stack had shown
similar performance and gas‐tightness compared to stacks
assembled with Crofer 22 APU. The post‐test
characterization had shown adhesive fracture patterns when
dismantling the stack parts.},
