Membrane catalyst layer assembly manufacturing method, membrane catalyst layer assembly manufacturing apparatus, and membrane catalyst layer assembly

摘要

A method for producing a membrane catalyst layer assembly capable of producing a membrane catalyst layer assembly having a catalyst layer having a desired porosity is provided. The porosity of a catalyst ink layer 140B formed by landing of the catalyst ink on the electrolyte membrane is controlled by adjusting the amount of solvent of the drop-shaped catalyst ink 140A before landing on the electrolyte membrane 110. To do. [Selection] Figure 3
