The ferritic AL453 steel is one of potential metallic interconnect materials for intermediate-temperature solid oxide fuel cells. However, the evaporation of chromium from the chromia scale formed on this steel and the increasing thickness of this scale result in the slow deterioration in the electrical properties of the interconnect’s elements. In order to improve fuel cell efficiency, the surface of the interconnect material was modified by applying a protective-conducting Mn1.5Co1.5O4 spinel coating. Thermal and electrical tests of the La0.8Sr0.2FeO3 cathode - AL453/Mn1.5Co1.5O4 interconnect system at 1073 K for 200 hrs in air confirmed the effectiveness of the spinel layers as a means of stopping chromium diffusion from the AL453 steel and inhibiting oxidation, while at the same time promoting electrical contact and minimizing cathode-interconnect interfacial resistance.

Hong et al. [ 7 ] showed that different volume fractions of iron nanoparticles in ethylene glycol were responsible for the determination of thermal conductivity in nanofluids. Shima et al.

performance compared to Ni-YSZ [ 13 ]. Moreover, Li et al. [ 14 ] reported M–Al 2 O 3 cermet supported tubular SOFC by thermal spraying while Hoboken [ 15 ] reported flame sprayed Ni–Al 2 O 3 wherein cermet coating played a dual role as a support tube and an anode current collector. The cell with the Ni–Al 2 O 3 catalyst layer showed significant improvement in performance, operating on both pure methane and methane oxygen mixtures of the gases. Furthermore, the cell performance deterioration rate was also greatly reduced even when operating on pure methane fuel [ 16
