【摘要】：采用相轉(zhuǎn)化流延一步制備了NiO-Zr0.84Y0.16O2-d(YSZ)陽(yáng)極支撐層和功能層,前者厚度為~700mm,含有沿厚度方向定向排列的開(kāi)放直孔,后者厚度為~60mm。采用漿料涂膜法和高溫共燒在陽(yáng)極上制備厚度為15mm的YSZ電解質(zhì)薄膜,絲網(wǎng)印刷制備YSZ-La0.84Sr0.16MnO3-d(LSM)(質(zhì)量比50:50)陰極。所制備的單電池顯示出較高的電輸出性能。以H2-3%H2O為燃料和環(huán)境空氣為氧化劑,800℃時(shí)電池的峰功率密度達(dá)到891mW/cm2,電池即使在高電流密度測(cè)試條件下也未出現(xiàn)明顯的濃差極化,這是由于其陽(yáng)極具有開(kāi)放直孔結(jié)構(gòu),氣相輸運(yùn)阻力小。
[Abstract]:NiO-Zr0.84Y0.16O2-dYSZ) anodic support layer and functional layer were prepared by a one-step phase conversion flow process. The former has a thickness of 700 mm and contains an open straight hole arranged in a directional direction along the thickness of NiO-Zr0.84Y0.16O2-dYSZ. The thickness of the latter is 60 mm. The YSZ electrolyte film with a thickness of 15 mm was prepared on the anode by slurry coating and high temperature co-firing. The cathode of YSZ-La0.84Sr0.16MnO3-dn / LSMU (mass ratio 50: 50) was prepared by screen printing. The single cell showed high electrical output performance. The peak power density of the cell reached 891 MW / cm ~ 2 even at high current density using H _ 2-3H _ 2O as fuel and ambient air as oxidant at 800 鈩，
