Abstract
The present invention provides a manufacturing method of a membrane electrode assembly which makes it possible to produce a polymer electrolyte fuel cell at a high level of productivity. According to the present invention, it is possible to make differences in characteristics between a first catalyst electrode 11A and a second catalyst electrode 11B, which are formed on the both surfaces of a polymer electrolyte membrane 3, without changing materials of the first and the second catalyst electrode 11A and 11B. In the present invention, the first and the second catalyst electrode 11A and 11B are adhered to the polymer electrolyte membrane 3 by sticking the first catalyst electrode 11A by a first roll press 7 followed by sticking the second catalyst electrode 11B by a second roll press 8.
Claims10
A method of manufacturing MEA by transferring a first catalyst electrode formed on a surface of a first support medium to one surface of a polymer electrolyte membrane and a second catalyst electrode formed on a surface of a second support medium to the opposite surface of said polymer electrolyte membrane, the method comprising:
- applying pressure with a first roll press to said first support medium and said polymer electrolyte membrane in their thickness direction so as to transfer said first catalyst electrode to said one surface of said polymer electrolyte membrane;
- and
- applying pressure with a second roll press to said second support medium and said polymer electrolyte membrane in their thickness direction so as to transfer said second catalyst electrode to said opposite surface of said polymer electrolyte membrane.
