(regularities are something like menses those are periodical or regular, sorry!) The aim of this work is to compare the strength and electrical conductivity of ceramics samples made of 8YSZ powder produced by different manufacturers: STC Novitek and Zirconia Ukraine Ltd. (Ukraine) and Tosoh Ltd.(Japan);to improve the tape casting method for production of anode-electrolyte half-cells with usingethylcellulose as a polymer and develop half-cell sintering regimes;to establish the dependence of SOFC electrical properties on the hydrogen concentration in the Ar-H2model fuel under the same other operation conditions. According to the work data,the Ukrainian 8YSZ powder is promising for the SOFC application.The samples made of the Ukrainian powder have demonstrated higher electrical conductivity and strength than that made of Japanese powder. The tape casting technique with ethylcelluloseused as a polymer for production of the anode-carrier and electrolyte-carrier at SOFC application was elaborated.The recommendations for the sintering modes for anode-electrolyte half-cell were formulated. The dependence of the SOFC power density at voltage 0.7 V and 600°C operation on the hydrogen concentration in the model fuel were established.
