摘要
An electrochemical device is described which has an oxygen electrode which contains a pyrochlore type electrocatalyst material. This electrocatalyst material is one or more electrically conductive pyrochlore compounds selected from the compounds of the following formula: ##EQU1## WHEREIN A is any of the known pyrochlore structure metal cations, B is a pyrochlore structure metal cation at least a major portion of which is selected from the group consisting of one or more of Ru, Rh, Ir, Os, Pt, Ru-Pb mixtures and Ir-Pb mixtures, and wherein O. ltoreq.y1.0. Desirably, A is a pyrochlore structure metal cation at least a major portion of which is selected from the group consisting of one or more of Pb, Bi and T1. A preferred group of pyrochlore compounds which are included in the above formula are those having the following formula: ##EQU2## WHEREIN M is selected from the group consisting of Ru and Ir, wherein OX1.2 and Oy. ltoreq.1.0.
