ABSTRACT:
Disclosed is an apparatus for making tubular-shaped membrane electrode assembly. The apparatus includes a guiding unit for guiding the direction of MEA production, a first weaving unit for weaving conductive fiber bundles into a first tubular conductive fabric around the guiding unit, a first catalyst-providing unit for forming a first catalyst film on the first tubular conductive fabric, a proton-exchange-membrane-providing unit for providing a proton-exchange-membrane on the first catalyst film, a second catalyst-providing unit for forming a second catalyst film on the proton-exchange-membrane, a second weaving unit for weaving conductive fiber bundles into a second tubular conductive fabric on the second catalyst film and a cooling and pulling unit for cooling and pulling the first tubular conductive fabric, the first catalyst film, the proton-exchange-membrane, the second catalyst film and the second tubular conductive fabric into a tubular laminate.
