Abstract
The supported NiYSZ 50 wt Ni + 50 wt Zr084Y016O192 anodes were produced of powders obtained by the ceramic method combustion synthesis deposition of nickel oxide onto the YSZ ceramics and deposition of 28 wt of nickel oxide onto the 39 wt NiO + 61 wt YSZ powders The influence of the NiOYSZ powder production technique the amount of pore former and sintering temperature on the porosity gas permeability thermal expansion and anode conductivity were studied The porosity of anodes made of powders obtained by the ceramic method is always lower than the porosity of the anodes made of powders produced by combustion synthesis under otherwise equal conditions The anode electrical conductivity greatly depends on the powder production techniques while the anode thermal expansion is only slightly influenced by themThe authors are grateful to AV Kuzmin for measuring linear thermal expansion of the anodes VA Eremin for preparation of samples for SEM AA Pankratov for the SEM microphotographs and MV Ananyev for image analysis The study is supported by the Program of UB RAS project № 12I3204
