Abstract:
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.

Claim (Index 16):
A membrane catalyst layer assembly production method 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 comprising:\n 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 changing a solid content concentration of the catalyst ink by adjusting an amount of solvent in the catalyst ink, and drying the catalyst ink by moving air in a periphery of droplets of the catalyst ink while airborne prior to impact with the electrolyte membrane in a discharge direction of the catalyst ink or in a circumferential direction along the discharge direction, 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 changing the solid content concentration of the catalyst ink by adjusting the amount of solvent in the catalyst ink, and drying the catalyst ink by moving air in the periphery of droplets of the catalyst ink while airborne prior to making impact with the first catalyst ink layer in a discharge direction of the catalyst ink or in a circumferential direction along the discharge direction.
