采用浆料旋涂法方法制作的致密YSZ薄膜矩形电池,在双气室和单气室都具有较好的性能输出.在氢气作为燃料的双气室条件下,电池的电流密度和电池功率密度都随着电池运行温度的提高而增加,当温度为800℃时,最大的功率密度达到了526 mW/cm2,最大电流密度达到了1．74 A/cm2；在通入甲烷、氧气、氮气混合气的单气室条件下,电池具有较好的选择催化性能,当甲烷和氧气气体比例m=1,温度为700℃时,功率密度最高,达到了160 mW/cm2.%Dense yttria-stabilized zirconia ( YSZ) membranes were fabricated on anode substrates of solid oxide fuel cell ( SOFC) using a slurry spin coating method. The cells were operated in both double chamber and single chamber conditions successfully. In double chamber conditions, the maximum current density and power density of the cell increased with the operated temperature. At 800℃, the maximum current density and power density were 1. 74 A/cm2 and 526 mW/cm2 , respectively. In single chamber conditions, the catalytic selectivity of the electrodes toward the CH4-O2-N2 gas mixture fulfilled the requirement of single chamber SOFC (SC-SOFC), and the highest maximum power density of the cell was about about 160 mW/cm2 at 700℃,CH4/O2=1.
