1. be supported with a manufacture method for the electrode catalyst for fuel cell of ternary system catalyst particle, it is characterized in that, comprising:

  • Dispersion step, by conductive carrier dispersion in the solution;

    Supporting procedures, drips platinum salting liquid, base metal salt solution and iridium salting liquid in this dispersion liquid, makes each slaine in the basic conditions as hydroxide loading in conductive carrier;

    And,Alloying step, by the conductive carrier of this carrying metal hydroxide heat reduction thus carry out alloying under reducing atmosphere,Also comprise;

    after described alloying step, use the acid of reproducibility to process the conductive carrier of the supported metal catalyst obtained by described alloying step, then use the acid of oxidizability to carry out the surface treatment procedure processed.
