Methods for Coating Electrode Materials

Electrode materials can be applied to SOFC substrates using a number of different methods. Menzler et al. [7] categorized the coating methods into three groups  

Substrate manufiicturing technique Geometry Thickness (pm) Slip/paste/suspension characteristics 

Tape casting Planar 100 800 Low viscosity (Pa s), azeotropic solvents, various organics 

Pressing Planar, microtubular Planar 500-2000, microtubular wall thickness 100—500 High viscosity, pressing agent, fewer organics 

Extrusion Planar, tubular, quasi-tubular Wall thickness 500 2000 High viscosity (1000 Pas), water-soluble binders, additional organics
