A SOFC providing higher power densities than PEM-based cells; the possibility
of
direct oxidation and/or internal reforming of fuel; and reduced SOFC operating
temperatures. The SOFC comprises a thin film electrolyte layer. A thick film anode
layer is disposed on one surface of the electrolyte layer; and a thick film cathode
layer is disposed on the opposite surface of the electrolyte layer. A method of
making the SOFC comprises the steps of: creating a well in one side of a dielectric
or semiconductor substrate; depositing a thin film solid oxide electrolyte layer
on the surface of the well; applying a thick film electrode layer in the electrolyte
coated well; creating a counter well in the opposite side of the substrate, the
counter well abutting the electrolyte layer; and applying a thick film counter
electrode layer in the counter well.
