Electrophoretic Impregnation/Deposition Complemented with Polymeric Templating for the Fabrication of Functionalized‐Porosity Layered‐Ceramics: A Solid‐Oxide‐Fuel‐Cells Approach

2011

A simple, economical, and environmentally compatible methodology for the fabrication of layered ceramics is presented herein. Water‐based electrophoretic techniques and polymeric templating were combined to fabricate graded‐porosity ceramic foams with controlled pore size, pore geometry, and excellent pore connectivity. Dense ceramic films can be laid either on top of the porous ceramic or in a sandwich‐style configuration. A single fabrication step suffices when working a single material (or material composition). Else, two or more fabrication steps are required. The two‐step manufacture of a half solid‐oxide‐fuel‐cell is presented. The yttria‐stabilized zirconia (8YSZ) solid electrolyte layer was deposited on top of the templated graded‐porosity nickel‐oxide/8YSZ electrode. The present methodology promises alternatives to current fabrication processes.
