METHOD FOR MANUFACTURING SOLID OXIDE FUEL CELL ANODE WITH HIGH STABILITY AND HIGH EFFICIENCY

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.
