Abstract

Composite materials containing metallic nickel and yttria stabilised zirconia (YSZ) have been prepared by a sol gel method. Microstructural investigations show that metal particles with a diameter of less than 300 nm still remain present after sintering. In the present work, the conductivity behaviour of such composites was investigated. Furthermore, ageing phenomena, in particular the influence of the nickel content, were studied. A possible application of such materials as anodes in solid oxide fuel cells will be discussed.
