چکیده انگلیسی
Here we report a novel SrFe0.75Mo0.25O3âδ (SFMO)-430L composite anode for the application in the metal supported solid oxide fuel cells. Such an anode is prepared by coating a thin nano porous and mixed electronic-ionic conducting SFMO layer onto the internal surface of a micron porous 430L alloy backbone. The area specific polarization resistance of the composite anode for hydrogen oxidation can be as low as 0.11 Ω cm2 at 800 °C. The electronic conductivity of the 430L alloy support is found to be critically important for promoting rapid hydrogen oxidation kinetics and attaining such a low polarization resistance as the fuel cell anode. A metal-supported fuel cell with the SFMO impregnated 430L composite anode exhibits outstanding power densities at 800 °C, e.g., 0.81 W cmâ2 in hydrogen and 0.31 W cmâ2 in iso-octane. Preliminary results show that the present SFMO-430L composite anode exhibits much higher tolerance for coking formation than the traditional Ni-based anode.
