      abstract     = {In the last few years, a lot of effort has been undertaken
                      to reduce the operation temperature of solid oxide fuel
                      cells (SOFCs). Intermediate temperatures in the range of
                      600-650 degrees C are thought to be highly attractive due to
                      the expected reduction of high-temperature corrosion and
                      interdiffusion phenomena. Furthermore, each stack operated
                      at higher temperatures has to pass this temperature range
                      during thermal cycling. In this work, a study has been
                      carried out to investigate the interaction between
                      interconnect steel (DIN 1.4760) and vermiculite mica paper
                      filled with talc at 600 degrees C. Mica paper has been
                      implemented recently as a new sealing material for SOFC
                      stacks, aiming to replace established but brittle glass
                      ceramics. Corrosion experiments were conducted at 600
                      degrees C under dual gas atmosphere conditions as well as in
                      air. The interconnect steel showed the formation of
                      non-protective oxide scales in contact with mica, especially
                      in the presence of air. The morphology of oxide scales was
                      investigated by SEM/EDX. Possible reasons for this
                      unexpected result are discussed. The complete encapsulation
                      of mica by embossed and welded sheets made of FeCrAlY-steel
                      (DIN 1.4767) as well as the pre-oxidation of interconnect
                      steel were investigated as solutions to this problem.
                      Pre-oxidation was found to be a promising measure to protect
                      the interconnect steel from breakaway oxidation in contact
                      with mica. (C) 2011 Elsevier B.V. All rights reserved.},
