<p>A solid oxide fuel cell component, such as a gas separator, which is adapted to be exposed to an oxidising atmosphere in the fuel cell system, and which is formed of a heat resistant alloy having a composition, in wt.%, of 5.0-10.0 Al, 0.1-3.8 Si, ≤ 0.5 Mn, ≤ 0.23 Cu, ≤ 0.61 Ni, ≤ 0.02C, ≤ 0.04 P, ≤ 0.045, < 5.0 Cr, and residue Fe. Preferably Cr ≤ 0.10 wt.%. In use the component has a thin, dense, adherent surface layer of Al2O3.</p> |
