Claim Text:
1. A method for manufacturing a solid oxide fuel cell anode with high stability and high efficiency comprising the steps of: preheating a porous permeable metal substrate; forming a diffusion barrier layer by atmospheric plasma spraying a plurality of first powder clusters over the porous permeable metal substrate; forming a nano-composite film by atmospheric plasma spraying a plurality of second powder clusters over the diffusion barrier layer, the second powder clusters consists of two kinds of anode materials and an organic adhesive binder; and reducing the nano-composite film by hydrogen reduction to reduce one of the two kinds of anode materials into a plurality of metal nanoparticles and form a plurality of nano gas pores and a plurality of nano gas channels in the nano-composite film, the remnants of the two kinds of anode materials are a plurality of metal oxide nanoparticles; wherein the size of the metal nanoparticle is smaller than 100 nm, the size of the metal oxide nanoparticle is smaller than 40 nm, and the sizes of the nano gas pore and the nano gas channel are smaller than 100 nm.
