摘要： A membrane catalyst layer assembly production method is provided for producing a membrane catalyst layer assembly by discharging catalyst ink having a solvent and a solid component onto an electrolyte membrane. The membrane catalyst layer assembly production method includes forming a first catalyst ink layer having a first porosity on the electrolyte membrane by controlling a porosity of a catalyst ink layer that is formed by the catalyst ink making impact with the electrolyte membrane by adjusting an amount of solvent in the catalyst ink in drop form prior to impact with the electrolyte membrane, and forming a second catalyst ink layer having a second porosity, which is different from the first porosity, on the first catalyst ink layer, by adjusting the amount of solvent in the catalyst ink in drop form prior to impact with the first catalyst ink layer.

摘要： An in-line coating device includes: a coating section configured to perform coating on a workpiece; and a transport section configured to transport a plurality of the workpieces in the coating section. The coating section is provided with a plurality of coating materials which are aligned. The transport section transports the workpieces such that the workpieces face the plurality of coating materials. The in-line coating device includes a voltage applying section configured to, when the workpiece is transported and faces each coating material, apply to the workpiece, a bias voltage to attract particles emitted from the coating material toward the workpiece. The bias voltages applied to the workpiece by the voltage applying section when the workpiece faces one of the coating materials can be different from that applied when the workpiece faces another one of the coating material.

摘要： 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.
