Abstract
Disclosed is a component for solid oxide fuel cells that is excellent in both electrical conductivity and chromium poisoning resistance. As a substrate, a ferritic stainless steel having a chemical composition containing, in mass %, Cr: 14.0% to 32.0% and Al: 2.50% to 7.00% is used. Precious metal particles are coated on a surface of the substrate. The precious metal particles have: an average particle size of 1 μm or more and 10 μm or less; a coating thickness of 0.5 μm or more and 10 μm or less; and a surface coverage of 1.0% or more.
