An interconnector (A1) for a high-temperature solid electrolyte fuel cell comprises : sintered chromium alloy formed with sintering pores, where the chromium alloy contains chromium (Cr) (greater than 90 wt.%), iron (Fe) (3-8 wt.%), aluminum (Al) (0.1-2 wt.%), optional at least one element (0.001-2 wt.%) selected from rare earth metals; and the sintering pores are at least partly filled with an oxidic compound containing Al and Cr. Independent claims are included for the following : (1) high-temperature solid electrolyte fuel cell comprising : ceramic solid electrolyte formed of stabilized zirconium oxide; and the interconnector (A1); (2) producing interconnector (A1) involving producing a powder mix from at least one of a mixed powder, partly pre-alloyed powder, and a fully pre-alloyed powder, shaping by die pressing at a pressing pressure set to 500-1000 MPa, optionally presintering at a temperature set to 700-1200[deg] C in a reducing atmosphere and optionally calibration pressing at a pressing pressure set to 500-1000 MPa, sintering at a temperature set to 1200[deg] C to solidus temperature in a reducing atmosphere, and oxidatively treating for producing the interconnector (A1).
