1. A method of manufacturing a membrane-electrode assembly, the method comprising:
feeding an electrolyte membrane by a feeding device;
applying a catalyst slurry to manufacture a first electrode onto a surface of the electrolyte membrane by an applicator, while feeding the electrolyte membrane by the feeding device;
performing drying of the catalyst slurry and heat treatment of the first electrode by applying heat to the electrolyte membrane by temperature control devices, while feeding the electrolyte membrane by the feeding device; and
transferring a second electrode to a remaining surface of the electrolyte membrane discharged from the feeding device, opposite to the surface of the electrolyte membrane having the first electrode bonded thereto, by a transfer device.
