<P>PROBLEM TO BE SOLVED: To provide a membrane electrode assembly for a tube type fuel cell having high current collecting efficiency and simple structure. <P>SOLUTION: The membrane electrode assembly for the tube-type fuel cell is equipped with at least a tube-shaped solid electrolyte membrane, an outside catalyst electrode layer formed on the outer peripheral surface of the solid electrolyte membrane, and an inside catalyst electrode layer formed on the inner peripheral surface. At least one of the inside catalyst electrode layer and the outside catalyst electrode layer is formed with carbon nano-tubes carried with a catalyst and an electrolyte material filled in gaps between carbon nano-tubes carried with the catalyst, and the carbon nano-tubes carried with the catalyst are arranged in the axial direction of the tube shape and in a degree capable of permeating gas. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
