Summary: This paper reviews the research on the new class of ionic conductors. Layered perovskite materials Ba(Sr)La(Nd)InO4 and various doped compositions have been investigated as oxygen-ion and proton conductors. The study found that doped and undoped layered perovskites exhibit mixed hole-ionic conductivity properties and can achieve proton conductivity in humid air.

Summary: Directionally solidified single crystals of (ZrO2)(1)(- x)(Y2O3)(x) solid solutions were grown, and the effect of stabilizing yttrium oxide concentration on their transport characteristics was studied. The crystal with a composition of (ZrO2)0.91(Y2O3)0.09 showed the highest electrical conductivity. Ceramic samples were prepared using the milled powder from this crystal, and the comparison between ceramic and single-crystal samples was conducted. The ionic conductivity of both materials was similar.

Summary: This study successfully synthesized bilayered anode-supported materials and bilayered gas-tight electrolyte through tape casting. The results showed that as the working temperature decreases, the contribution of electrode processes to the cell's internal resistance increases, resulting in a decrease in specific power.

Summary: The influence of the surface topology of the Ce0.9Gd0.1O1.95 solid electrolyte, formed by laser processing, on the electrochemical activity of the Pr1.95La0.05CuO4 cathode material in oxygen reduction reaction is studied. The ordered columnar structure with a relief profile depth of approximately 11-12 μm is found to be the most preferable for achieving higher electrochemical activity.

Summary: The substitution of 5% ferroactive molybdenum cations for iron in the La0.6Sr0.4Co0.2Fe0.8O3 - delta (LSCF) structure significantly increases the electric conductivity. Using powder X-ray diffraction, the researchers identified the solubility limit of molybdenum in rhombohedral perovskite structure. It was found that the transport characteristics of La0.6Sr0.4Co0.2Fe0.75Mo0.05O3 - delta (LSCFM5) make it suitable as a cathode material in intermediate temperature solid oxide fuel cells (IT SOFCs).

Summary: This study presents the results of the R&D of electrochemical components for an energy system based on hydrogen-air open cathode fuel cells with proton-exchange membrane. The study shows that this system can achieve a high specific energy electrical power system by using self-humidification of the membrane with reaction water, without the need for humidifiers and heaters, and using light metals as the material for the bipolar plates. Additionally, the study investigates methods for improving the electrochemical components to achieve higher power modulus.

Summary: The electrical conductivity of fluorite-type Ce1-x-yLaxPryO2-delta solid solutions was studied, and it was found that (Ce,La)O2-delta exhibits predominant anion conductivity with oxygen ion transference numbers above 0.99 over the entire temperature range. The decrease in oxygen partial pressure leads to an increase in n-type electronic conduction, and the concentrations of point defects and their diffusivities were calculated under reductive conditions.

Summary: The La0.6Sr0.4Co0.8Fe0.2O3-delta-Ce0.73Gd0.27O2-delta composite cathodes (LSCF-GDC) were prepared using nanopowders through a method of mixing precursors followed by sintering. The optimal sintering temperature was found to be 1100 degrees C, and no secondary phases were formed even at 1400 degrees C. The characteristics of the LSCF-GDC cathodes degrade with the increase in the GDC fraction. The addition of GDC nanopowder accelerates the sintering process, resulting in a denser cathodic structure and increased polarization resistance.

Summary: The high-temperature performance of microtubular LSCF membrane was studied using the operando high-temperature X-ray diffraction method. It was found that the outer surface of the membrane closely resembles the structure of LSCF powder at the same oxygen concentration, whether the feed gas is delivered outside the membrane or the external surface is blown around by pure helium.

Summary: Protonic ceramic fuel cells (PCFCs) are a promising energy technology that can efficiently convert chemical energy into electric power at reduced temperature. The practical use of PCFCs relies on efficient key cell materials, such as electrolyte and electrodes, that meet various requirements. In the past two decades, researchers have extensively explored complex oxides with the ABO(3) perovskite or related structure as key materials in PCFCs due to their flexible composition and versatile properties. The material engineering of perovskite oxides for PCFCs is an important focus of research, with a particular emphasis on compositional engineering to modify the lattice structure, defect structure, and ionic transportation behavior of perovskite oxides.
