Abstract:
1. An apparatus for making tubular-shaped membrane electrode assembly comprising: 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; 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 that can be cut into tubular-shaped membrane electrode assembly of appropriate lengths.
