Process for producing fuel cell electrode by applying a sugar to a precursor supporting a metal oxide and conductive substance and carbonizing the sugar

摘要

The invention provides catalysts that are not corroded in acidic electrolytes or at high potential, have excellent durability and show high oxygen reducing ability. In a process of producing fuel cell electrodes containing a metal oxide and an electron conductive substance, the process includes steps in which a sugar is applied and carbonized on a support layer supporting the metal oxide and the electron conductive substance.

1. A process for producing fuel cell electrodes, comprising first to fourth steps described below:
First step:
a step in which a precursor (A) is produced by supporting a metal oxide and an electron conductive substance on a support layer; Second step:
a step in which a precursor (B) is produced by applying a sugar to the precursor (A) obtained in the first step; Third step:
a step in which a precursor (C) is obtained by carbonizing the sugar contained in the precursor (B); and Fourth step:
a step in which a fuel cell electrode is produced by applying a polymer electrolyte to the precursor (C) obtained in the third step.
