ABSTRACT:
Single-component bodies useful in fuel cells and other electrochemical devices are provided. In preferred embodiments, the single-component bodies comprise an anodic region at a first side, a cathodic region at a second, non-adjacent side, and an oxygen ion-conducting region substantially free from anodic or cathodic character disposed between said anodic and cathodic regions. The single-component bodies comprise oxide electrolytes such as yttria-stabilized zirconia doped with multivalent cations such as titanium or terbium.
