Methods for manufacturing membrane electrode assembly for a proton exchange membrane electrochemical cell

A method for manufacturing a membrane electrode assembly for an electrochemical cell, the method comprising:

• providing a first substrate including a first film coated from one or more polymeric materials;
• coating a first electrode on the first substrate;
• coating a first membrane layer on the first electrode;
• providing a second substrate including a first film coated from one or more polymeric materials;
• coating a second electrode on the second substrate;
• coating a second membrane layer on the second electrode;
• arranging a sub-gasket between and in contact with a periphery of the first membrane layer and the second membrane layer;
• and
• hot pressing the first membrane layer against the second membrane layer with the sub-gasket arranged at least partially therebetween.
