A dense, electronically conductive interconnection layer (26) is bonded on a porous, tubular, electronically conductive air electrode structure (16), optionally supported by a ceramic support (22), by (A) forming a layer of oxide particles of at least one of the metals Ca, Sr, Co, Ba or Mg on a part (24) of a first surface of the air electrode (16), (B) heating the electrode structure, (C) applying a halide vapor containing at least lanthanum halide and chromium halide to the first surface and applying a source of oxygen to a second opposite surface of the air electrode so that they contact at said first surface, to cause a reaction of the oxygen and halide and cause a dense lanthanum-chromium oxide structure to grow, from the first electrode surface, between and around the oxide particles, where the metal oxide particles get incorporated into the lanthanum-chromium oxide structure as it grows thicker with time, and the metal ions in the oxide particles diffuse into the bulk of the lanthanum-chromium oxide structure, to provide a dense, top, interconnection layer (26) on top of the air electrode (16). |
