[Problems] To easily and efficiently manufacture a catalyst layer having high catalytic activity and to easily manufacture a fuel cell having high power generation efficiency. [Solution] An apparatus for forming a catalyst layerfor a fuel cell on an electrolyte film (application object), the apparatus including: a holding portionthat holds a sheet-shaped electrolyte film, an application portionthat applies a catalyst inkfor forming the catalyst layeron at least one side of the electrolyte filmheld by the holding portion, a chamber portionthat is capable of forming a spaceincluding the holding portion, and a suction portionthat depressurizes the inside of the spaceformed by the chamber portionso as to dry the catalyst ink

Catalyst-layer forming apparatus

A method is provided that modifies a catalyst layer of a membrane catalyst layer assembly, which is manufactured by transferring the catalyst layer formed on a transfer sheet onto an electrolyte membrane. In the catalyst layer correction method, presence or absence of a defect in the catalyst layer is detected. The defect is removed based on the size and position of the detected defect. The portion from which the defect has been removed is repaired by application thereto of a correcting ink corresponding to the catalyst layer.
