The present invention provides an intelligent MEA for fuel cell including means for easily measuring the voltage of unit cells and means for preventing heat transfer from an outside low-temperature heat source to a catalyst layer of the MEA during operation of the fuel cell stack at low temperature. For this, the present invention provides n intelligent membrane electrode assembly (MEA) for fuel cell, including: an MEA in which a catalyst layer is coated on both sides of an ion exchange membrane, and an ion exchange membrane support film is attached on both sides of an edge portion of the ion exchange membrane; a flexible printed circuit board (PCB) mounted on one surface of the ion exchange membrane support film along the outer line of the catalyst layer of the MEA; a PCB terminal formed on one end of the flexible PCB; and a connector connected to the PCB terminal to communicate with an external controller, wherein the flexible PCB includes an electrical heating element, an electrical heating element temperature sensor for measuring the temperature of the electrical heating element, an MEA temperature sensor for measuring the temperature of the MEA, an electrical contact for measuring the resistance of unit cells, and an electrical contact for measuring the voltage of the unit cells, formed in a predetermined arrangement to communicate with the PCB terminal.
