To provide electrode catalyst (core-shell catalyst) having an excellent catalyst activity which contributes to lower the cost of the PEFC. The electrode catalyst has catalyst particles supported an a support. The catalyst particle has a core part containing simple Pd and a shell part containing simple Pt. A percentage R.sub.C (atom %) of the carbon of the support and a percentage R.sub.Pd (atom %) of the simple Pd in an analytical region near a surface measured by X-ray photoelectron spectroscopy (XPS) satisfy the conditions of the following equation (1): 2.15≦[100×R.sub.Pd/(R.sub.Pd+R.sub.C)].

A reaction device comprising: a first flow path to which a fuel gas is supplied; a second flow path to which a gas containing oxygen is supplied; a hydrogen permeable membrane that separates the first flow path and the second flow path and allows hydrogen contained in the fuel gas supplied to the first flow path to permeate toward the second flow path; and a catalyst that is provided in the second flow path and promotes oxidation reaction between the oxygen and hydrogen passing through the hydrogen permeable membrane, wherein the hydrogen permeable membrane comprises a barium zirconium oxide membrane.

The present invention relates to a mixed oxide of aluminium, of zirconium, of cerium, of lanthanum and optionally of at least one rare-earth metal other than cerium and lanthanum that makes it possible to repair a catalyst that retains, after severe ageing, a good thermal stability and a good catalytic activity. The invention also relates to the process for preparing this mixed oxide and also to a process for treating exhaust gases from internal combustion engines using a catalyst prepared from this mixed oxide.
