ANODE-SUPPORTED SOLID OXIDE FUEL CELL COMPRISING A NANOPOROUS LAYER HAVING A PORE GRADIENT STRUCTURE, AND A PRODUCTION METHOD THEREFOR

摘要

The present invention relates to a solid oxide fuel cell having a gradient structure in which pore size becomes gradually smaller from a porous electrode to an electrolyte thin film in order to form a dense electrolyte thin film of less than about 2 microns and preferably less than 1 micron on the porous electrode.
