1. A heat treatment apparatus of a membrane-electrode assembly for a fuel cell, comprising:
a hot press disposed between front and rear feeding roller assemblies and configured for feeding a membrane-electrode assembly sheet along a feed path and pressing an electrode catalyst layer portion on upper and lower surfaces of the membrane-electrode assembly sheet at a predetermined temperature;
a plurality of gripper modules installed at predetermined intervals along a feeding direction of the membrane-electrode assembly sheet and gripping both side edges of the membrane-electrode assembly sheet; and
a cooling unit installed in the rear feeding roller assembly to inject cooling air to the membrane-electrode assembly sheet,
wherein the front and rear feeding roller assemblies each include upper and lower feeding rollers rotatably mounted on front and rear roller brackets, and wherein the cooling unit is installed on the rear roller bracket and is configured to inject cooling air to an opposite side of the feeding direction through the upper and lower feeding rollers on a rear side.
