Abstract
Disclosed is an apparatus for manufacturing a fuel cell. When blanking a continuous membrane electrode assembly (MEA) into individual MEAs and then bonding the individual MEAs to a sub-gasket, a scrap electrolyte membrane located at the continuous MEA is prevented from being bonded to a sub-gasket by release-purpose surface roughness formed on a surface thereof, so that it is possible to prevent manufacturing defects of the fuel cell. Further, when the individual MEAs are bonded to the sub-gasket, the continuous MEA is intended to be well bonded to the sub-gasket up to edge portions of the individual MEAs by the pressing force of a pattern roll.
Claims11
An apparatus for manufacturing a fuel cell, the apparatus comprising:
- a blanking section configured to perform blanking on a continuous membrane electrode assembly (MEA) withdrawn from an MEA winding roll into individual MEAs and to form surface roughness for endowing a slippage characteristic and a water repellent characteristic on a surface of a scrap electrolyte membrane;
- a bonding roll configured to bond a sub-gasket withdrawn from a sub-gasket winding roll to the individual MEAs;
- and
- a variable control roll configured to press the continuous MEA transferred from the blanking section toward the bonding roll, and configured to selectively bond only the individual MEAs of the continuous MEA to the sub-gasket.
