Plasma-sprayed coatings in solid oxide fuel cells
Fuel cells are highly efficient and environmentally friendly electrochemical energy converters and will be of increasing significance in the future parallel to the development of hydrogen as a carrier of energy for a society oriented to regenerative energy supply. In the article, it is shown that plasma spraying may be a useful process for the commercial manufacturing of solid oxide fuel cells. Electrode and electrolyte coatings as well as spinel-titanium coatings for the brazing, sealing and insulation of fuel cell stacks are presented as possible applications. The advances made here in the last few years in relation to the power density and the long-time stability towards the industrially relevant fabrication of solid oxide fuel cells are highlighted.
