Abstract
It becomes easy to regulate the storage modulus of the ionomer solution to be not lower than 150 Pa. The production method of catalyst ink for fuel cell includes steps of: (i) preparing a catalyst dispersion by mixing an electrode catalyst, water and an alcohol; (ii) preparing a gelated ionomer solution by mixing an ionomer and a solvent; and (iii) producing catalyst ink by mixing the catalyst dispersion and the gelated ionomer solution, wherein the step (ii) comprises concentration a step of concentrating the gelated ionomer solution.
