| Abstract | X-ray diffraction and scanning electron microscopy were used to study the chemical compatibility of (La, Sr)CrO3, SrCrO4, CaCrO4 and Cr2O3 (materials associated with the interconnect of a solid oxide fuel cell) with gadolinia-doped cerium oxide electrolyte (CGO). Powder mixtures and multilayer pellets of the interconnect related materials were annealed with CGO in air at temperatures ranging from 650 to 1600°C for durations of up to 400 h. No reaction was observed between (La,Sr)CrO3 and Ce0.8Gd0.2O1.9 after annealing at 1600°C for 10 h. However, SrCrO4, CaCrO4 and Cr2O3 reacted with CGO, forming an unidentified phase. |
