Abstract: An object of the invention is a protection method of solid oxide cells, in which method is arranged gas flows in the cell by at least two cell structure plates made of metal. In the method is formed metal oxide material on metallic structure from liquid precursor containing at least metal ions and at least one of organic and inorganic compounds fed into thermal flame having average gas velocity over 200 m/s.

Abstract: A protection arrangement including the first coating and another coating on metal structure of solid oxide cells, each solid oxide cell having at least two fuel cell structure plates made of metal to arrange gas flows in the cell, and an active electrode structure, which includes an anode side, a cathode side, and an electrolyte element between the anode side and the cathode side. The protection arrangement can include: a first metal oxide coating on a metallic structure in a first thermal spraying coating process of a liquid precursor being from at least one of nitrates and acetates based substances fed into thermal flame; and at least one other metal oxide coating formed at least partly simultaneously with the first coating process on the previously deposited metal oxide coating from a liquid precursor.
