Title:
METHOD FOR MANUFACTURING MEMBRANE ELECTRODE ASSEMBLY FOR FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2018/062972
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a membrane electrode assembly for a fuel cell, in which uniform pressure is applied to the entire area of an electrode during a transferring process to ensure uniformity of products. The method for manufacturing a membrane electrode assembly for a fuel cell according to the present invention comprises: an electrode forming step of forming an electrode layer by coating an electrode slurry on a support; a transfer step of aligning the electrode layer on both surfaces of an electrolyte membrane and applying heat and pressure to transfer the electrode layer; and removing the support, wherein in the transfer step, gas pressure is applied to a gas pressure platen of a stretchable material to transfer the electrode layer to the electrolyte membrane. The present invention allows uniform pressure to be applied to the entire area of the electrode during the transferring process to ensure uniformity of products, thereby improving the quality and improving the performance of the fuel cell.
