以BaCe0.9Y0.1O3-α氧化物陶瓷为固体电解质,以多孔性Pt为电极材料,组成氢-空气燃料电池,用电流遮断法分别测定了600℃～1000℃范围燃料电池输出电流时的欧姆电位降和正负极的电极极化 结果表明,该燃料电池的优良性能与Pt电极很小的极化作用密切相关,正负极的电极极化皆随着温度的升高而变小,正极的极化小于负极的极化 With BaCe0.9Y0.1O3-α oxide ceramic as solid electrolyte and porous Pt as electrode material, a hydrogen-air fuel cell was composed. The current intercept method was used to determine the output current of the fuel cell in the range of 600 ℃ ~ 1000 ℃ Potential drop and positive and negative electrode polarization results show that the excellent performance of the fuel cell is closely related to the small polarization of the Pt electrode, the positive and negative electrode polarization are smaller with increasing temperature, the positive pole Less than the polarization of the negative
