      abstract     = {In order to gain insight into the mechanism causing
                      performance degradation and/or failure, stacks of planar
                      solid oxide fuel cells (SOFC) are routinely dismantled and
                      examined after operation at Forschungszentrum Julich. The
                      post-operation inspection focuses in particular on the
                      chemical and mechanical compatibility aspects of cell and
                      stack materials.In the present work a short-term degradation
                      effect is addressed, which was found to be caused by
                      unwanted chemical interactions between glass-ceramic
                      sealants and ferritic steel interconnects. The
                      post-operation inspection revealed severe steel corrosion
                      along the seal rims. Under SOFC stack conditions rapidly
                      growing oxide nodules were observed bridging the 200 mu m
                      seal gal) between the metallic components after a few
                      hundred hours of operation. These oxide nodules, rich in
                      iron, gave rise to local short-circuiting effects eventually
                      resulting in stack failure.The present study, combined with
                      recent model investigations triggered by the stack results,
                      indicates that severe degradation only occurs in the case of
                      glass-ceramic sealants which contain minor amounts of PbO.
                      Furthermore, the rate of corrosion attack of the metallic
                      components strongly depends on the silicon (Si) content of
                      the ferritic steel. The stack tests suggest that increasing
                      the Si content increases the corrosion rate, and thus
                      detrimentally influences the stack performance. (c) 2005
