Notes:
Plasma spray processing is a low-cost, rapid manufacturing technique that is widely usedindustrially for fabrication of thermal barrier and wear- and corrosion-resistant coatings. Becausethe technique can be used to rapidly deposit coatings of high melting temperature materials withgood substrate adhesion, it has also been applied to the production of individual component layersin tubular solid oxide fuel cells (SOFCs), and more recently, in planar SOFCs. The use of plasmaspray processing for the fabrication of fuel cell components presents unique challenges, due to thehigh porosities required for the electrode layers and fully dense coatings required for electrolytes.Application of plasma spray processing for the manufacture of solid oxide fuel cells is discussed,with consideration of potential advantages of the technique compared to standard SOFC wetceramic processing routes. Major challenges faced in the adaptation of the processing method tosolid oxide fuel cell manufacture are discussed, along with current research approaches being usedto overcome these challenges. Recent developments in the use of the technique for the rapid onestepmanufacturing of direct oxidation SOFC anodes are discussed, for composite materialcombinations that cannot be co-sintered due to widely divergent melting points. The impacts ofplasma sprayed coating properties on solid oxide fuel cell performance are considered, andimplications of the use of the technique on overall stack and system manufacturing costs arediscussed
