Influence of Microstructure and Sintering Routes on Transport Properties of Apatite Materials for Fuel Cells
Authors:A.Chesnaud C.Estournes G.Dezannau
Abstract:1 Results Oxy-apatite materials are thought as zirconia-substitutes in Solid Oxide Fuel Cells due to their fast ionic conduction. However, the well known difficulties related to their densification prevent them from being used as such. This study presents strategies to obtain oxy-apatite dense materials and the influence of elaboration route on transport properties. Particular emphasis is put on the microstructure effect on ion conduction. By the combined use of freeze-drying and conventional or spark p...
