Area specific resistance of oxide scales grown on ferritic alloys for solid oxide fuel cell interconnects

Planar solid oxide fuel cells (SOFC) are considered to be power generators with high efficiency and low emission at small power units (1–200 kW el). Many prototype systems are already successfully realized. For mass production the costs have to be reduced and the long-term stability has to be enhanc...
