Apparatus for manufacturing membrane electrode assembly

Abstract

An apparatus for manufacturing a membrane electrode assembly to selectively drive / stop by checking whether temperature control of transfer rolls is normal is provided. The apparatus includes transfer rolls, the temperature of which is controlled by a temperature control unit, to pass a transfer film on which a polymer electrolyte membrane and electrodes are formed therebetween in order to press the transfer film and to transfer the electrodes onto the polymer electrolyte membrane; a thermochromic pigment inserting device installed at a front end of the transfer rolls to coat the thermochromic pigment on the polymer electrolyte membrane; a color information acquiring unit installed at the rear side of the transfer rolls to acquire color change information of the thermochromic pigment; and a controller to check whether temperature control of the transfer rolls is normal from the color change information of the thermochromic pigment acquired by the color information acquiring unit.

Description

technical field [0001] The present invention relates to an apparatus for manufacturing a membrane electrode assembly, and more particularly, to an apparatus for manufacturing a membrane electrode assembly by checking whether the temperature of a transfer roll is properly controlled so as to automatically select a driving mode and a stop mode . Background technique [0002] A fuel cell is a generator that does not burn the chemical energy of fuel to convert chemical energy into heat, but converts chemical energy into electrical energy through electrochemical reactions in the battery pack. Fuel cells can be used for commercial purposes and for powering homes, and are also suitable for supplying small electrical / electronic devices, portable devices, and power to start vehicles. [0003] As an existing power source for starting a vehicle, among fuel cells, a polymer electrolyte membrane fuel cell (PEMF) having the highest power density is generally studied. [0004] A PEMF con...

Problems solved by technology

However, although temperature sensors are installed in the equipment such that the temperature sensors are properly associated with the heating means (by simple on / off of the heating means sensing the temperature), the existing equipment does not include detection when the temperature sensor fails. Auxiliary device for transfer roller temperature

[0018] In particular, since existing equipment for manufacturing membrane electrode assemblies does not include a system for monitoring the temperature control state of the transfer roller and checking whether there is any abnormality in the temperature control so as to take immediate emergency measures if necessary, the product Inferiority increases, so it is necessary to reduce defective products by detecting the failure of the temperature control of the transfer roller
