Abstract:
A method for producing a gold fine particle-supported carrier catalyst for a fuel cell, which reduces a gold ion in a liquid phase reaction system containing a carbon carrier by means of an action of a reducing agent, to reduce the gold ion, deposit, and support a gold fine particle on the carbon carrier, wherein a reduction rate of the gold ion is set within the range of 330 to 550 mV/h, and pH is set within the range of 4.0 to 6.0 to perform the reduction of the gold ion, deposition, and support of the gold fine particle.
