Fabrication and performance of anode-supported micro-tubular solid oxide fuel cells

Abstract

A solid oxide fuel cell was fabricated using standard NiI/8YSZ cermet anode, 8 mol % yttria stabilized zirconia (YSZ) electrolyte, and lanthanum strontium manganite cathode. The anodes were extruded using an hydraulic ram extruder An electrolyte was deposited using a novel technique allowing obtaining a 3-5 mu m thin and dense YSZ layer. The cathode was deposited by brush painting. The cells were operated under different temperature and fuel conditions, and showed excellent performance of up approximately 0.6 W cm(-2) at 890 degrees C. Performance data as well as scanning electron microscopy micrographs of the cells are presented.
