Abstract
An apparatus for production of a fuel cell catalyst layer forming a catalyst layer by a catalyst paste, the apparatus including a device for removal of water to obtain a polyelectrolyte solution by reducing, to a predetermined value or less, the concentration of water in a pre-solution in which a polyelectrolyte having a side chain including a hydrophilic functional group is dissolved in a solvent; and an agitator means for obtaining the catalyst paste by mixing a pre-paste obtained by mixing a catalyst with water and the polyelectrolyte solution.
