Cover Story: Solid oxide fuel cell (SOFC) anode materials require mixed ionic and electronic conduction properties. This is achieved in perovskite oxides with SrMo1−xAlxO3−δ composition. A neutron powder diffraction investigation showed that they are cubic (s.g. Pm-3m), displaying a random distribution of Mo and Al cations over the octahedral sites of the structure. This results in conspicuous amounts of oxygen vacancies in the perovskite, detected by neutrons at the working conditions of a SOFC. Oxygen deficiency is essential to induce ionic diffusion. Indeed, these defective perovskites outperform as anode materials in test fuel cells, providing substantial output power densities. They are, thus, a good replacement of conventional biphasic cermet anodes in SOFC. View this paper
