<P>PROBLEM TO BE SOLVED: To solve a problem that, in case a coating method or a screen printing method hitherto used for forming an interface layer which sometimes are to be provided between an electrode catalyst layer and a gas diffusion layer for a membrane/electrode assembly for a solid oxide fuel cell equipped with the same on either side of a solid polymer film, condensation of carbon as a main component of an interface layer tends to take place, and as a result, a void ratio on the interface layer is decreased to degrade output concentration of cells. <P>SOLUTION: In the manufacturing method of the membrane/electrode assembly for a solid polymer fuel cell, voltage is impressed between a blowout nozzle 1 and a conductive substrate 2, a material solution 3 for forming a porous interface layer is sprayed by an electrostatic spraying method from the blowout nozzle 1 on a base material 4 made of a porous carbon base material or an electrode catalyst layer to form a porous interface layer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
