  "textContent": "There is provided a method for manufacturing a catalyst ink for fuel cell electrodes that allows simultaneously performing fineness of a catalyst and adjustment of viscosity of the catalyst ink. The method for manufacturing a catalyst ink for fuel cell electrodes containing a catalyst, a solvent, and an ionomer includes stirring and mixing the catalyst, the solvent, and the ionomer by a high-shear thin-film spin mixer. The ionomer contains a gel-like ionomer. The high-shear thin-film spin mixer includes a cylindrical stirring tank, a rotary vane, and a shaft. The cylindrical stirring tank has unevennesses on an inner peripheral surface. The rotary vane is concentric with the stirring tank and has an outer diameter slightly smaller than an inner diameter of the stirring tank. The shaft includes the rotary vane on an end portion and is rotatable at high speed in forward and reverse directions.",
