Tape casting high-density electrolyte for solid oxide fuel cells

This work has shown that high-density, impermeable, thin YSZ structures can be produced by tape casting. The most important parameters in developing the tape casting process were found to be the YSZ powder characteristics, the binder-solvent system, the dispersant which must be compatible with the solvent/binder system, adequate milling to assist dispersion, and the proper solids loading to minimize firing shrinkage.
