【摘要】:多孔Pt/YSZ(YSZ,氧化釔穩(wěn)定的氧化鋯)電極中Pt的含量對電阻膜層性能起決定作用.以0.1μm、0.5μm Pt粉和YSZ為原料并控制其質(zhì)量比,制備電極漿料并燒結(jié)成電極膜層;測其電阻及表面形貌.實(shí)驗(yàn)證明:多孔Pt/YSZ電極中,Pt顆粒越細(xì),電極膜層電阻越小,電極性能也越穩(wěn)定;當(dāng)Pt/YSZ的質(zhì)量比達(dá)到最佳比例時,電極電阻較小,且Pt/空氣/YSZ三相邊界面積達(dá)到最大,電極催化活性最好.
[Abstract]:The Pt content in the porous Pt- / YSZ- YSZ (yttrium stabilized zirconia) electrode plays a decisive role in the performance of the resistive film.Using 0.5 渭 m Pt powder and YSZ as raw materials and controlling the mass ratio, the electrode paste was prepared and sintered to form an electrode film, and its resistance and surface morphology were measured.The experimental results show that the finer the Pt particles in the porous Pt/YSZ electrode, the smaller the film resistance and the more stable the electrode performance is, when the mass ratio of Pt/YSZ reaches the optimum ratio, the electrode resistance is smaller, and the Pt/ / YSZ three-phase boundary area reaches the maximum.The electrode has the best catalytic activity.
