“…It may be presumed that this effect is a consequence of an effective reinforcement of the matrix not only by inclusions based on TiN or Ti(C,N), but also by numerous precipitates of silicon and titanium oxides located near the surface layer of the steel. These oxides were formed as a results of internal oxidation of silicon and titanium during long-term oxidation of the studied ferritic steel [17]. However, the proper investigation of this effect would require significantly longer cyclic oxidation, i.e.…”

The paper presents the results of investigations of the physicochemical and mechanical properties of the Crofer 22 APU steel designed for application in metallic interconnects forming the key components of solid oxide fuel cells (SOFCs). Microstructural and hardness studies of non-metallic inclusions and the matrix were carried out. Based on compression tests of raw Crofer 22 APU and the steel after 600 hrs of cyclic oxidation in air at 800°C, the composition of non-metallic inclusions and their influence on the strength properties of the steel were determined.

Interconnect-cathode interfacial adhesion is important for the durability of solid oxide fuel cell (SOFC). Thus, the use of a conductive contact layer between interconnect and cathode could reduce the cell area specific resistance (ASR). The use of La 0.6 Sr 0.4 FeO 3 (LSF) cathode, LaNi 0.6 Fe 0.4 O 3-d (LNF) contact layer and Crofer22APU interconnect was proposed as an alternative cathode side. LNF-LSF powder mixtures were heated at 800°C for 1,000 h and at 1,050°C for 2 h and analyzed by X-Ray power diffraction (XRD). The results indicated a low reactivity between the materials. The degradation occurring between the components of the half-cell (LSF/ LNF/Crofer22APU) was studied. XRD results indicated the formation of secondary phases, mainly: SrCrO 4 , A(B, Cr)O 3 (A = La, Sr; B = Ni, Fe) and SrFe 12 O 19 . Scanning electron microscopy with energy dispersive X-Ray spectroscopy (SEM-EDX) and the X-Ray photoelectron spectroscopy (XPS) analyzes confirmed the interaction between LSF/LNF and the metallic interconnect due to the Cr vaporization/migration. An increment of the resistance of~0.007 Ω cm 2 in 1,000 h is observed for (LSF/LNF/Crofer22APU) sample. However, the ASR values of the cell without contact coating, (LSF/Crofer22APU), were higher (0.31(1) Ω cm 2 ) than those of the system with LNF coated interconnect (0.054(7) Ω cm 2 ), which makes the proposed materials combination interesting for SOFC.
