Abstract
A method for manufacturing a membrane electrode assembly includes an applying step of applying a catalyst ink to a first surface of a polymer electrolyte membrane, and a drying step of drying the applied catalyst ink. The applying step is performed in a state where a second surface of the polymer electrolyte membrane opposite to the first surface is in contact with a swelling solvent that swells the polymer electrolyte membrane.
Claims9
A method for manufacturing a membrane electrode assembly, the method comprising:
- applying a catalyst ink to a first surface of a polymer electrolyte membrane;
- and
- drying the catalyst ink that has been applied,
- wherein the applying is performed in a state where a second surface of the polymer electrolyte membrane opposite to the first surface is in contact with a swelling solvent that swells the polymer electrolyte membrane.
An apparatus for manufacturing a membrane electrode assembly, the apparatus comprising:
- a solvent storage unit configured to store a swelling solvent;
- a frame-shaped jig provided on the solvent storage unit, the frame-shaped jig being configured to bring a polymer electrolyte membrane into contact with the swelling solvent while supporting a peripheral edge portion of the polymer electrolyte membrane;
- an applying device disposed above the polymer electrolyte membrane and configured to apply a catalyst ink to the polymer electrolyte membrane;
- and
- a drying device configured to heat and dry the catalyst ink applied to the polymer electrolyte membrane,
- wherein the drying device is disposed rearward of the applying device in a direction of relative movement of the applying device relative to the polymer electrolyte membrane.
