Polymer Electrolyte Fuel Cell, Membrane Electrode Assembly and Manufacturing Method Thereof

A method for manufacturing an MEA in which a polymer electrolyte membrane is arranged between a first electrode catalyst layer and a second electrode catalyst layer, comprising;

• coating a first catalyst ink, which contains catalyst loaded particles, a polymer electrolyte and a solvent, on a substrate to form a coated layer of said first catalyst ink;
• removing said solvent in said coated layer of said first catalyst ink to form a first electrode catalyst layer;
• coating an electrolyte ink, which contains a polymer electrolyte and a solvent, on said first electrode catalyst layer to form a coated layer of said electrolyte ink;
• removing said solvent in said coated layer of said electrolyte ink to form a polymer electrolyte membrane;
• coating a second catalyst ink, which contains catalyst loaded particles, a polymer electrolyte and a solvent, on said polymer electrolyte membrane to form a coated layer of said second catalyst ink;
• and
• removing said solvent in said coated layer of said second catalyst ink to form a second electrode catalyst layer.
