Abstract
This chapter presents a state-of-art brief review on anode materials for SOFC. Materials, processing and synthesis routes to attain porous anodes are highlighted. Especial attention is given to Ni-ceramic phase (especially fluorite-type structure ceramics) cermets. Some aspects about prospects and problems of the currently developed electrodes materials are elucidated. Electrodes for intermediate temperature SOFCs (IT-SOFCs) are discussed in relation to other conventional electrodes. The electrochemical characterization of anodes, as mixed ionic-electronic conductors, is briefly outlined.
Keywords: Anodes, Ceramics, Cermets, chemical routes, conventional routes, Electrical properties, Electrodes, Mixed Ionic-Electronic Conductor, Porous, Solid Oxide Fuel Cell.
