Abstract
A manufacturing system and method of an membrane electrode assembly (MEA) for a fuel cell is provided which increases performance and durability of an MEA and ensures productivity of the MEA therein. In particular, electrodes and an electrolyte membrane are bonded together and the membrane electrode assembly manufactured in the bonding process is pressed at a predetermined temperature.
Claims13
A method of manufacturing a membrane electrode assembly for a fuel cell, comprising:
- a bonding process that bonds electrodes and an electrolyte membrane to form the membrane electrode assembly;
- and
- a heat treatment process presses the membrane electrode assembly after the bonding process at a given temperature,
- wherein several membrane electrode assemblies are vertically stacked and the interfacial adhesion between electrodes and an electrolyte membrane of each membrane electrode assembly is increased by simultaneously pressing the membrane electrode assemblies at a given temperature, in the heat treatment process, and
- wherein a protection paper is inserted in between a hot press and the membrane electrode assembly, and between each vertically stacked membrane electrode assembly of the vertically stacked membrane electrode assemblies, in the heat treatment process.
