Zusammenfassung:	PCT No. PCT/DE95/00026 Sec. 371 Date Oct. 29, 1996 Sec. 102(e) Date Oct. 29, 1996 PCT Filed Jan. 10, 1995 PCT Pub. No. WO95/19053 PCT Pub. Date Jul. 13, 1995A boundary layer structure, useful in a fuel cell, includes a solid electrolyte and an electrode. The electrode consists essentially of a perovskite base material and a platinum group metal oxide addition, along the boundary between the perovskite and the electrolyte. Iridium oxide is a preferred metal oxide addition material, while a preferred perovskite is lanthanum ferrite, which contains Sr and either Co or Mn.
