<P>PROBLEM TO BE SOLVED: To provide a membrane electrode assembly in which impedance is low and crossover is suppressed, and a fuel cell using the membrane electrode assembly, and a manufacturing method of the membrane electrode assembly in which manufacturing of the membrane electrode assembly becomes easy. <P>SOLUTION: This is the membrane electrode assembly 1 equipped with a fuel electrode 4, an oxidizer electrode 3, and an electrolyte membrane 2 arranged between the fuel electrode 4 and the oxidizer electrode 3. The electrolyte membrane 2 includes an inorganic porous membrane 6 that has a through hole 5 in which the thickness is ≤1 μm, that is penetrated in the thickness direction, and the average value of a hole diameter size of the through hole 5 is the thickness size or less, and includes a proton conductive electrolyte 7 filled into the through hole 5 of the inorganic porous membrane 6. <P>COPYRIGHT: (C)2009,JPO&INPIT |
