<P>PROBLEM TO BE SOLVED: To provide a catalyst slurry composition, or the like, in which the pore size can be controlled easily while having a large surface area and a high porosity, and which improves the performance and the lifetime of a fuel cell. <P>SOLUTION: The catalyst slurry composition for fuel cell electrode which forms a porous catalyst layer from which spherical silica is removed by treating a catalyst layer, formed by coating a support with a catalyst slurry composition, with alkali solution contains 5-about 30 parts by weight of binder polymer and 6-about 70 parts by weight of silica for 100 parts by weight of active metal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
