XRD pattern indicated that BSCN crystallized in a singlephase perovskite with a cubic perovskite structure (Pm3m) and no evident reaction happened after the mixture of BSCN cathode and GDC electrolyte was sintered at 1 000 ℃ for 10 h. During the operating temperature of SOFCs (600~800 ℃), the electrical conductivity of BSCN reaches 21~27 S/cm. The thermal expansion coefficient value of 17.0 × 10-6/K has been measured for BSCN sample, which is much lower than that of SrCo0.9Nb0.1O3δ(SCN). This result indicated that Ba doping in SCN has a better thermal match to GDC electrolyte. Symmetrical cell with the configuration of BSCN/GDC/BSCN was used for the impedance measurements. The polarization resistance of BSCN cathode on GDC electrolyte is 0.026 Ω·cm2 at 750 ℃. With BSCN cathode, NiOCe0.8Sm0.2O1.9 anode and 300 μm thick GDC electrolyte, the maximum power density of single cell achieved 782 mW/cm2 at 800 ℃.

As the cement slurry hydration speed is slow, the curing time is long and the increase of cement early compressive strength is slow in the low temperature cementing of conductor and surface casing, it is easy to result in oil, gas and water invasion which impairs cementing quality and operation safety. In view of the fact that the accelerator is lack in cementing of low temperature shallow formation currently at home, some accelerators have poor effectiveness and significant negative impact on slurry rheology etc, a new compound accelerator WSA1 was selected by laboratory study. The performance of slurry that mixed WSA1 was systematically evaluated. The result shows that the accelerator WSA1 can enhance the hydration of oil well cement, shorten the thickening time of cement slurry and significantly improve the early compressive strength of cementstones, which all accord with the requirement of the accelerator evaluation criterion. When WSA1 addition amount is 3%, the thickening time of cement slurry can be shortened more than 50%, the 6 h strength of cementstones enhanced from 3.2 MPa to 11.3 MPa and the 24 h strength of cementstones enhanced from 24.3 MPa to 46.1 MPa.
