Application of Electrochemical Deposition in Solid Oxide Fuel Cell Technology3 Ceramist

This review paper describes the principle of electrochemical deposition and introduces recent studies applying it to the electrode fabrication of a solid oxide fuel cell (SOFC), a next-generation energy conversion device. Electrochemical deposition can easily control the structure and morphology of the deposition layer according to the applied bias/time/temperature, etc., and the process is very simple and possible even at low temperatures. In addition, deposition of cerium-based oxides, which are the representative ion-conductors or mixed-conductors widely used for SOFCs, is also possible via electrochemical deposition. To elucidate the effectiveness/novelty of electrochemical deposition, we present examples of the application of electrochemical deposition in SOFCs. Moreover, examples of using this method to study the properties of a material and/or to fabricate perovskite oxide-based electrodes are included.
