Oxidation of porous stainless-steel coated with donor-doped SrTiO3 in anodic atmosphere of solid oxide fuel cell
چکیده انگلیسی
This study evaluates the effect of donor-doped SrTiO3 (La0.2Sr0.8Ti0.9Ni0.1O3-δ, LSTN) coating on chromia growth on the surface of porous stainless steel (STS). During subsequent exposure to wet H2 atmosphere at 800 °C, the porous STS oxidizes, and its Ohmic resistance increases slowly for 300 h to an area-specific resistance (ASR) ∼2.5 mΩ cm2, but at a much slower rate does uncoated STS and to a much lower ASR than that of uncoated STS (∼17.9 mΩ cm2). The estimated parabolic rate constant indicates that the porous LSTN-coated STS may be used at temperature <680 °C for ∼10 y.
