In this study, Bi 2 O 3 couple system sample materials were synthesized using solid state reaction method sintering each of them. Structural and electrical properties of these electrolyte samples for solid oxide fuel cells (SOFCs) have been evaluated by means of XRD, TG / DTA, SEM and four-probe method. In this work, (Bi 2 O 3 )1-x-y(Dy 2 O 3 )x(Ho 2 O 3 )y tenary systems have been investigated. As a result of XRD measurements, δ (cubic)-phase samples were obtained with a stable structure. As a results of electrical conductivity measurements, (Bi 2 O 3 )1-x-y(Dy 2 O 3 ) x (Ho 2 O 3 ) y tenary system, increase Dy 2 O 3 molar ratio corresponds to a fixed molar ratio of Ho 2 O 3 conductivity value falls was obtained.
