The electrical and thermal properties of composite cathode materials Pr1–xSrxFe1–yCoyO3 (x = 0.3, 0.4; y = 0.2): GDC and La2Ni1-xCoxO4+δ (x = 0.2):GDC for solid oxide fuel cells (SOFC) were investigated. As the second component of the composites, GDC electrolyte was chosen. The reason for this choice is that GDC has greater chemical inertness in relation to cathode materials compared to YSZ. Additionally, GDC is characterized by higher ionic conductivity, which makes it preferable for use in composites. The sintering kinetics of composite materials differs significantly from that of pure cathode materials, with the sintering temperature being several degrees lower for composite materials. © (2024), (L.N.
