This study aimed to investigate oxidation, electrical and mechanical properties of solid oxide fuel cell interconnects. To this goal, two different Crofer®22 interconnects samples were produced via different manufacturing routes (machining from bulk material, and powder metallurgy approach). The samples were characterized by scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS), X-ray diffractions. Four-probe area specific resistance (ASR), bonding strength, leakage tests were also performed. The results indicated that interconnect sample manufactured through powder metallurgy approach can be a reliable alternative to the one manufactured from commercially available Crofer®22 alloy in bulk form.
