| Abstract: |
| 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 (10μm)/LSM-YSZ was successfully prepared 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 resistance of the electrolytic cell can be effectively reduced through thinning down of YSZ electrolyte membrane with screen-printing technology. |
