Abstract
An electricity-generating assembly (EGA) fabrication apparatus includes a downstream press. The downstream press includes an attachment roll configured to attach a second gas diffusion layer (GDL) to a second surface of a membrane-electrode assembly (MEA) with a first GDL attached to a first surface of the MWA. The attachment roll is rotatable and is configured to receive the second GDL having a predetermined size and attach the GDL to the second surface of the MEA at predetermined distances.
Claims19
An electricity-generating assembly (EGA) fabrication apparatus comprising:
- a downstream press, wherein the downstream press comprises an attachment roll configured to attach a second gas diffusion layer (GDL) to a second surface of a membrane-electrode assembly (MEA) with a first GDL attached to a first surface of the MWA;
- wherein the attachment roll is rotatable and configured to receive the second GDL having a predetermined size, and to attach the GDL to the second surface of the MEA at predetermined distances.
An electricity-generating assembly (EGA) fabrication method comprising:
- continuously supplying a membrane-electrode assembly (MEA) by an MEA unwinding part;
- attaching a first gas diffusion layer (GDL) to a first surface of the MEA using an upstream press disposed upstream in a flow direction of the MEA, wherein the first GDL is continuously supplied;
- attaching a second GDL to a second surface of the MEA using a downstream press disposed downstream in the flow direction of the MEA;
- and
- obtaining an EGA by attaching the second GDL to the MEA.
