Electrode catalyst layer manufacturing equipment and manufacturing method

Japanese Patent JP6350030

B2

PROBLEM TO BE SOLVED: To provide a manufacturing device and a manufacturing method for an electrode catalyst layer from which agglomerate is sufficiently removed.SOLUTION: A manufacturing device 100 for an electrode catalyst layer has an application head 130 for applying electrode catalyst ink 40, which constitutes the electrode catalyst layer, to a film base material 90. The application head 130 has a supply port 132, a manifold part 134, agglomerate removal means 140, and a discharge port 136. The electrode catalyst ink 40 is supplied to the supply port 132. The manifold part 134 widthwise spreads the electrode catalyst ink 40 introduced from the supply port 132. The agglomerate removal means 140 is arranged in the manifold part 134 and crushes and/or collects agglomerate contained in the electrode catalyst ink 40. The discharge port 136 allows the electrode catalyst ink 40, passed through the manifold part 134 and the agglomerate removal means 140, to discharge toward the film base material 90.
