Embodiment Construction

[0044] Below, while referring to the appendix Figure 1 Embodiments of the present invention will now be described.

[0045]

[0046] figure 1 A diagram showing a configuration of an apparatus 1 for producing a membrane-electrode assembly according to an embodiment of the present invention. The manufacturing apparatus 1 is an apparatus for manufacturing a membrane-electrode assembly for a solid polymer fuel cell by forming an electrode layer on the surface of the electrolyte membrane 90 while conveying the electrolyte membrane 90 as a long strip-shaped thin film. like figure 1 As shown, the manufacturing apparatus 1 of the membrane-electrode assembly of the present embodiment includes a suction roll 10 , a porous base material supply and recovery unit 20 , an electrolyte membrane supply unit 30 , an electrode layer forming unit 40 , and an assembly having a sticking unit 50 . Recovery unit 60 and control unit 70 .

[0047] The suction roll 10 is a roll that rotates while...

Abstract

The present invention provides a technique for attaching a support membrane to a hydrocarbon-based polymer electrolyte membrane in the production process of the membrane-electrode assembly. The support film (93) is a support film attached to the hydrocarbon-based polymer electrolyte membrane (90), and one surface of the support film (93) has adhesive force. The hydrocarbon-based polymer electrolyte membrane has lower adhesiveness than the conventional fluorine-based polymer electrolyte membrane. Therefore, even if the conventional PET film or PEN film used as the support film is directly subjected to the thermal lamination process, the electrolyte membrane and the support film do not stick to each other, and the electrolyte membrane cannot be properly supported. Therefore, by using a film having adhesive force on the surface as the support film (93), it can be attached to the hydrocarbon-based polymer electrolyte membrane (90) and supported appropriately.

Description

technical field [0001] The present invention relates to a support membrane attached to a hydrocarbon-based polymer electrolyte membrane, a method of attaching the support membrane to a hydrocarbon-based polymer electrolyte membrane, and formation of an electrode layer on the surface of the hydrocarbon-based polymer electrolyte membrane The manufacturing method and manufacturing apparatus of the membrane-electrode assembly. Background technique [0002] In recent years, fuel cells have been attracting attention as driving power sources for automobiles, mobile phones, and the like. Fuel cells are made of hydrogen (H 2 ) and oxygen in the air (O 2 ) electrochemical reaction between the power generation system to generate electricity. Compared with other batteries, fuel cells have the characteristics of high power generation efficiency and less burden on the environment. [0003] Fuel cells are classified into several types according to the electrolyte used. One of the fuel...
