<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrode/membrane junction for a fuel cell capable of securing power generating performance of the electrode/membrane junction of the fuel cell. <P>SOLUTION: The manufacturing method of an electrode/membrane junction is to structure an anode side base layer 22 to be coated on an anode side diffusion layer 21 with carbon 28, a binder, and a solvent 29, and to coat the anode side base layer 22 on the anode side diffusion layer 21 with its surface levelled with a blade 44, with a particle size of the carbon of 0.1 to 10 μm, a solid content ratio of the anode side base layer of 2 to 20 wt.%, and a viscosity of the same 22 of 0.05 to 1 Pa s, provided that a value obtained with the sum of mass of the carbon 28, the binder and the solvent 29 as a denominator and the sum of mass of the carbon 28 and the binder as a numerator is called the solid content ratio. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
