ABSTRACT:
A nanostructured composite anode with nano gas channel and an atmosphere plasma spray manufacturing method thereof are disclosed. The anode consists of a porous base material and a composite film with nano gas channels above the porous base material while the composite film has a plurality of nano gas pores and a plurality of nano gas channels. The manufacturing method according to the present invention includes the steps of: provide micron-sized agglomerated and nanostructured powders having mixture of nano oxide particles and a binder; heat the micron-sized agglomerated and nanostructured powders into melt or semi-melt oxide mixture; spray the melt or semi-melt oxide mixture on a porous base material; and generate the nanostructured anode composite film with nano gas channels through hydrogen reduction. The anode of the present invention increases the electrochemical activity and slows down nickel particle aggregation effect under high temperature environment.
