本文依据固体氧化物燃料电池(SOFC)于运作条件下的基本性能,诸如化学稳定性、电迁移、催化和热机械性能等评述SOFC组成部分(电极材料和电解质)的基本性质.示明由氧偏离化学计量比引起的电极材料结构缺陷与其电子性质及催化活性之间的相互关系,提出单室燃料电池概念.

The paper summarizes and discusses the basic properties of solid oxide fuel cell(SOFC) components(electrode materials and electrolyte) from the point of view of their essential functional parameters suck as chemicalstability,transport,catalytic and thermomechanical properties under operational conditions in a SOFC.An interrela-tion between the defect structure of these materials related to oxygen nonstoichiometry and their electronic propertiesand catalytic activity was shown.Single-chamber fuel cell concept was also presented.
