摘　　要：采用一种冷烧结辅助烧结工艺制备Ni-YSZ半电池,使得电解质和阳极的共烧结温度由1400℃降低至1200℃,同时又能保证YSZ电解质在该温度下保持足够的致密度。半电池的共烧结温度下降能减小NiO颗粒尺寸,提高电池三相界面(TPB)长度,进而提高单电池的电性能。以氢气为燃料,空气作为氧化剂,分别对冷烧结工艺制备的单电池和传统烧结制备的单电池进行电性能测试,在800℃时的最大功率密度分别为0.474 W·cm^(-2)和0.207 W·cm^(-2)。The Ni-YSZ half-cell was prepared by a cold sintering-assisted sintering process,so that the co-sintering temperature of the electrolyte and the anode was reduced from 1400℃to 1200℃,and the YSZ electrolyte maintained sufficient density at this temperature.The decrease of the co-sintering temperature of the half cell can reduce the size of NiO particles and increase the length of the three-phase interface(TPB)of the cell,thereby improving the electrical performance of the single cell.The electrical performance of single cells prepared by cold sintering process and conventional sintering process were tested using hydrogen as fuel and air as oxidant,and the maximum power densities at 800℃ were 0.474 W·cm^(-2) and 0.207 W·cm^(-2),respectively.
