Device for manufacturing membrane-electrode gasket assembly

A device for manufacturing a membrane-electrode gasket assembly, the device comprising:

• a first sub-assembly configured to manufacture a membrane-electrode body having a membrane and an electrode catalyst being joined to each other;
• a second sub-assembly provided downstream from the first sub-assembly and being configured to receive the membrane-electrode body from the first sub-assembly, the second sub-assembly comprising a second moving roller capable of moving in an up-down direction;
• and
• a third sub-assembly provided downstream from the second sub-assembly, the third sub-assembly being configured to receive the membrane-electrode body from the second sub-assembly and to manufacture an assembly by joining a gasket to the membrane-electrode joined body,
• wherein the membrane is disposed continuously over the first to third sub-assemblies,
• wherein the third sub-assembly comprises a heat-pressing part configured to heat or press the membrane-electrode body,
• wherein the heat-pressing part comprises:
• a first pressing roller facing one surface of the membrane-electrode body;
• a second pressing roller facing the first pressing roller with the membrane-electrode body therebetween;
• a third pressing roller facing the second pressing roller with the membrane-electrode body therebetween,
• wherein the second pressing roller is disposed above the first pressing roller, and the third pressing roller is disposed above the second pressing roller,
• wherein the heat-pressing part further comprises:
• a fourth pressing roller that faces the third pressing roller;
• a fifth pressing roller that faces the second pressing roller;
• and
• a sixth pressing roller that faces the first pressing roller,
• wherein the fourth pressing roller is provided on a right side of the third pressing roller,
• wherein the fifth pressing roller is provided on a right side of the second pressing roller,
• wherein the sixth pressing roller is provided on a right side of the first pressing roller,
• wherein the first sub-assembly comprises:
• a first slot die being configured to apply a first electrode catalyst to a surface of the membrane;
• a first dryer configured to dry the membrane and the first electrode catalyst;
• and
• a second slot die being configured to apply a second electrode catalyst to the other surface of the membrane,
• wherein the first dryer comprises:
• a drying body:
• a first drying space formed in the drying body, wherein the membrane and the first electrode catalyst are configured to flow into the first drying space;
• and
• a second drying space formed in the drying body, wherein the membrane, the first electrode catalyst, and the second electrode catalyst are configured to flow into the second drying space,
• wherein the first drying space and the second drying space are spaced apart from each other in the up-down direction inside the drying body, and
• wherein the first drying space and the second drying space are configured to be in an overlapping state when the first dryer is viewed from the above,
• wherein the third sub-assembly comprises an assembler provided downstream from the heat-pressing part, the assembler being configured to press and join the membrane-electrode body and the gasket,
• wherein the assembler comprises:
• a first joining member configured to press the membrane-electrode body and the gasket to form a first joined region in the membrane-electrode gasket assembly;
• and
• a second joining member configured to press the membrane-electrode body and the gasket so as to form a second joined region in the membrane-electrode gasket assembly, wherein the first joined region is different from the second joined region,
• wherein a direction in which the membrane-electrode gasket assembly is conveyed is referred to as a front-rear direction, the first joining member presses a front region or a rear region of the gasket, and
• wherein the second joining member presses a left region or a right region of the gasket.
