    摘要： A nanostructured anode of solid oxide fuel cell with high stability and high efficiency and a method for manufacturing the same are revealed. This anode comprising a porous permeable metal substrate, a diffusion barrier layer and a nano-composite film is formed by atmospheric plasma spray. The nano-composite film includes a plurality of metal nanoparticles, a plurality of metal oxide nanoparticles, and a plurality of gas pores that are connected to form nano gas channels. The metal nanoparticles are connected to form a 3-dimensional network that conducts electrons, while the metal oxide nanoparticles are connected to form a 3-dimensional network that conducts oxygen ions. The network formed by metal oxide nanoparticles has certain strength to separate metal nanoparticles and prevent aggregation or agglomeration of the metal nanoparticles. Thus this anode can be applied to a solid oxide fuel cell operating in the intermediate temperatures (600˜800° C.) with high stability and high efficiency.

    摘要： The disclosure provides a double-layer anode structure on a pretreated porous metal substrate and a method for fabricating the same, for improving the redox stability and decreasing the anode polarization resistance of a SOFC. The anode structure comprises: a porous metal substrate of high gas permeability; a first porous anode functional layer, formed on the porous metal substrate by a high-voltage high-enthalpy Ar—He—H2—N2 atmospheric-pressure plasma spraying process; and a second porous anode functional layer, formed on the first porous anode functional layer by a high-voltage high-enthalpy Ar—He—H2—N2 atmospheric-pressure plasma spraying and hydrogen reduction. The first porous anode functional layer is composed a redox stable perovskite, the second porous anode functional layer is composed of a nanostructured cermet. The first porous anode functional layer is also used to prevent the second porous anode functional layer from being diffused by the composition elements of the porous metal substrate.
