Abstract
Fundamental aspects of how films of the SrZr0.95Y0.05O3–δ electrolyte are formed from alcoholic-aqueous solutions of salts at various solution characteristics (salt concentration, viscosity, and relative content of water) were studied. It was found that, to obtain dense film electrolytes, it is necessary to use low-viscosity solutions with the minimum content of water. The revealed fundamental aspects will make it possible to obtain dense film membranes based on strontium zirconate for solid-oxide fuel cells by the technologically simple solution method. Solutions with high content of water can be used to form an external porous layer on the surface of a dense membrane, which must favor an increase in the power of fuel cells.
