A method for depositing solid electrolyte layer includes the steps of depositing a solid electrolyte layer on an electrode substrate by an electrophoretic deposition process, firing the solid electrolyte layer at a temperature of 1,300.degree. C. or less, and depositing another electrolyte layer on the fired solid electrolyte layer by a CVD-EVD process. In accordance with the method, thin and sufficiently dense solid electrolyte layers which are suitable for solid electrolyte fuel cells can be easily produced.

A method for manufacturing a thin zirconia film comprises the steps: (a) preparing a suspension in which partially-stabilized or stabilized zirconia particles having electric charges are dispersed in a solvent; (b) positioning a pair of electrodes in the suspension; (c) applying an electric field between the electrodes, said zirconia particles moving to the electrode and said zirconia particles being deposited on the electrode electrochemically; and (d) sintering the zirconia film to form a partially-stabilized or stabilized thin zirconia film.
