abstract = {The efficiency of a solid oxide fuel cell (SOFC) can be
improved by using a Ni-mesh between the ferritic steel
interconnect and the Ni/YSZ anode. However, interdiffusion
processes can lead to internal oxidation within the Ni-mesh
and some microstructural changes, i.e., formation of an
austenite zone and accelerated formation of σ-phase at the
ferrite/austenite interface. These changes may adversely
affect the performance of the cell during long-term
operation. The present work focused on the influence of
certain alloying elements on the overall behavior of the
ferritic steel under simulated SOFC operating conditions to
define conditions to minimize σ-phase formation without
degrading the oxidation resistance and mechanical properties
of the steel. The experimental results indicate that
decreasing the amount of Cr and adjusting the amount of Nb,
Si and W of the steel is a possible way to achieve that
goal.},
