Abstract

A manufacturing method for a catalyst layer for a fuel cell includes: preparing a nozzle group to output ultrasonically-vibrated air, the nozzle group being formed of an aggregate of unit nozzles each controlled in at least one of the temperature of the ultrasonically-vibrated air to be output from the unit nozzle, an internal pressure in the unit nozzle, and the position of the unit nozzle in an output direction in which the ultrasonically-vibrated air is to be output; coating a sheet-like base material with catalyst ink containing a solvent, an ionomer, and a catalyst supporting material on which a catalyst is supported; and drying the catalyst ink by blowing the ultrasonically-vibrated air from the nozzle group on the catalyst ink applied to the base material. The drying includes controlling at least one of the temperature, the internal pressure, and the position for each of the unit nozzles independently.
