Abstract
An electrically conductive ceramic layer is deposited on a porous body. The porous body is formed of sintered Fe-based alloy grains and has a density of 40 to 70% of its theoretical density. The electrically conductive deposition layer preferably has a perovskitic structure and it is formed by a pulsed sputtering process. The layer has a low diffusivity for the elements in the iron group and is especially suitable for use in solid oxide fuel cells (SOFC).
