Abstract:
A method for producing a catalyst ink, by which the surface of a catalyst can be appropriately covered with an ionomer, and the power generation performance of a fuel cell can be excellent in a wide range of humidity environments, and a catalyst composite. The method for producing a catalyst ink may comprise the steps of, for a catalyst composite in which a catalyst is supported on a carbon support with pores, controlling a hydrophilic pores rate of the carbon support to 60% to 80%, and dispersing an ionomer in the catalyst composite after the controlling step, wherein the hydrophilic pores rate is calculated by the following formula (1) using a contact porosimetry method: Hydrophilic pores rate (%)=(hydrophilic pores volume/total pores volume)×100   Formula (1)

Claim (Index 3):
The method for producing the catalyst ink according to  claim 1 , wherein the controlling step includes at least one step selected from the group consisting of the steps of:\n acid treating the support in a range of from room temperature to 80\u00b0 C. with a nitric acid solution, before the catalyst is supported on the support; firing the support in a temperature range of from 150\u00b0 C. to 2600\u00b0 C. in an oxygen-containing gas atmosphere, before the catalyst is supported on the support; bringing the catalyst and the nitric acid solution into contact with the support when the catalyst is supported on the support; and firing the catalyst composite obtained by supporting the catalyst on the support, in a temperature range of from 150\u00b0 C. to 500\u00b0 C. in an inactive gas or reducing gas atmosphere.
