    摘要:

    采用液料等離子噴涂方法 (SPPS)制備固體氧化物燃料電池多孔La0.8Sr0.2MnO3 (LSM)陰極。用SEM觀察LSM的微結(jié)構(gòu)，用XRD研究其相結(jié)構(gòu)?？疾炝藝娡烤嚯x和熱處理溫度對LSM微結(jié)構(gòu)的影響規(guī)律。結(jié)果表明，SPPS LSM 在1050 ℃熱處理2 h后形成連續(xù)的具有微納介孔結(jié)構(gòu)的涂層，且LSM具有單一的鈣鈦礦結(jié)構(gòu)。利用電化學交流阻抗譜方法研究了LSM極化行為。微結(jié)構(gòu)對極化性能有顯著影響，1000 ℃時，LSM在噴涂距離為60 mm時具有最佳的電化學性能，陰極極化電阻約為0.3 Ω·cm2。通過工藝的控制，SPPS可以實現(xiàn)SOFC陰極相和微結(jié)構(gòu)的優(yōu)化

    Abstract:

    Solution precursor plasma spraying (SPPS) was employed to prepare porous La0.8Sr0.2MnO3 (LSM) cathode for solid oxide fuel cell (SOFC). The surface morphology and microstructure of the LSM deposits were characterized by SEM. The phase structure of LSM was analyzed by XRD. The electrochemical behavior was investigated through the impedance spectroscopy. The effect of spray distance and annealing treatment on SPPS LSM microstructure was examined. Annealing at 1050 oC for 2 h in air, the coherent porous films of the perovskite phase with a fine microstructure were presented. The results show that the microstructure of SPPS LSM cathode exhibits a significant influence on the cathode polarization. The lowest specific surface resistance of 0.3 Ω·cm2 is obtained at 1000 oC for SPPS LSM cathode deposited at a spray distance of 60 mm. SPPS is a promising process to fabricate SOFC cathode with tailoring of the desired phase and microstructure
