Abstract

Electrocatalytic material comprising at least one reduced platinum group metal oxide is subsequently heated in the presence of oxygen at a temperature high enough to stabilize the catalyst in acidic and halogen environments. The catalyst optionally contains thermally stabilized oxides of transition or valve metals, nitrides, carbides or sulphides thereof, and graphite. A gas permeable electrode structure includes particles of the catalyst and a polymeric binder. A method of preparing the electrocatalytic material is described as well as a unitary electrolyte electrode structure which has a gas permeable electrode containing thermally stabilized particles of the electrocatalytic material, bonded to at least one side of a membrane-electrolyte.
