<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a mixed electrode-catalyst material for a solid electrolyte fuel cell capable of reducing manufacturing costs of an electrode catalyst and a fuel cell by largely reducing an amount of platinum as compared with the conventional electrode-catalyst of a platinum material. <P>SOLUTION: The manufacturing method of a mixed electrode-catalyst material for a solid electrolyte fuel cell includes a stage (a) of pouring hydrogen used as a reducing agent in advance after an RuOs alloy material highly dispersed in a crystallized nano-particle form is dispersed into water and an unnecessary gas is removed by pouring nitrogen, a stage (b) of pouring platinum precursor solution into solution where the RuOs alloy material is dispersed and pouring hydrogen additionally for one hour after completing pouring of the platinum precursor, and a stage (c) of obtaining a powdery material through washing and drying processes after completing the pouring of hydrogen. <P>COPYRIGHT: (C)2009,JPO&INPIT |
