Apparatus and method for manufacturing membrane-electrode assembly of fuel cell

A method of the apparatus for manufacturing a membrane-electrode assembly for a fuel cell, the method comprising:

• (a) unwinding an electrolyte membrane sheet from an electrolyte membrane sheet roll, recovering a protect film attached on an electrolyte membrane, and supplying the electrolyte membrane along a set feed path;
• (b) unwinding a first electrode film sheet including a first electrode film continuously coated with an anode electrode layer and a second electrode film sheet including a second electrode film coated with a cathode electrode layer with a predetermined gap, and supplying the first electrode film sheet and the second electrode film sheet along the set feed path;
• (c) passing the electrolyte membrane and the first and second electrode film sheets through between a driving bonding roll and a driven bonding roll, and transferring the anode electrode layer and the cathode electrode layer of the first and second electrode films to upper and lower surfaces of the electrolyte membrane, respectively;
• (d) sensing an edge position of the cathode electrode layer through a first position sensor, sensing an edge position of an embossing portion of the driving bonding roll through a second position sensor, and outputting sensed signals to a controller;
• and
• (e) moving the driven bonding roll away from the driving bonding roll and increasing or decreasing a relative rotational position of the driving bonding roll with respective to the driven bonding roll by controls of the controller based on the sensed signals of the first and second position sensors so as to adjust the positions of the anode electrode layer and the cathode electrode layer.
