摘　　要：采用丝网印刷法制备了Y2O3稳定ZrO2(YSZ)电解质薄膜,并对固体氧化物电解池(SOEC)的NiO-YSZ氢电极预烧温度进行了优化。结果表明,NiO-YSZ氢电极适宜的预烧温度为1 000℃,YSZ电解质薄膜化后制备的SOEC在800℃、850℃和900℃三种电解温度下,1.50V时的产氢速率分别为386mL/(cm2.h)、255mL/(cm2.h)和142mL/(cm2.h)。采用丝网印刷法将YSZ电解质薄膜化制备后可以有效降低电解池的欧姆阻抗。Yttria-stabilized zirconia （YSZ） electrolyte film was prepared by screen-printing technology. The presintering temperature of porous NiO-YSZ hydrogen electrode substrates used in solid oxide electrolysis cells （SOEC） was optimized. A single fuel cell of Ni-YSZ/YSZ （10 μm）/LSM-YSZ was successfully pre- pared by screen-printing method. The results show that the optimum presintering temperature of NiO-YSZ hydrogen electrode is 1 000 ℃, and the hydrogen production rate of single SOEC is 386 mL/（cm2·h）, 255 mL/（cm2·h）, and 142 mL/（cm2·h）, at 800 ℃, 850 ℃ and 900 ℃, respectively. The ohmic resist- ance of the electrolytic cell can be effectively reduced through thinning down of YSZ electrolyte membrane with screen-printing technology.
