METHOD AND APPARATUS FOR PRODUCING MEMBRANE ELECTRODE ASSEMBLY |
摘要 |
A technique for producing a membrane electrode assembly with high quality is provided. In a method for producing a membrane electrode assembly, a first catalyst layer of a first catalyst layer sheet is bonded to a surface of an electrolyte film on which an electrolyte film base sheet is not formed. A first catalyst layer base sheet is separated from the first catalyst layer. The electrolyte film base sheet has been separated from the electrolyte film. A second catalyst layer of a second catalyst layer sheet is bonded to a surface of the electrolyte film from which the electrolyte film base sheet has been separated. The method for producing a membrane electrode assembly further includes a preliminary step of bonding either the second catalyst layer formed on the second catalyst layer base sheet or the second catalyst layer base sheet to a portion of the electrolyte film that has been fed prior to a position at which bonding of the first catalyst layer starts. |

1. A method for producing a membrane electrode assembly, the method comprising:
a feeding step of feeding an electrolyte film sheet including an electrolyte film base sheet and an electrolyte film formed on the electrolyte film base sheet, a first catalyst layer sheet including a first catalyst layer base sheet and a first catalyst layer formed on the first catalyst layer base sheet, and second catalyst layer sheet including a second catalyst layer base sheet and a second catalyst layer formed on the second catalyst layer base sheet; a first bonding step of bonding the first catalyst layer of the first catalyst layer sheet to a surface of the electrolyte film on which the electrolyte film base sheet is not formed; a first separation step of separating the first catalyst layer base sheet from the first catalyst layer; a second separation step of separating the electrolyte film base sheet from the electrolyte film; and a second bonding step of bonding the second catalyst layer of the second catalyst layer sheet to a surface of the electrolyte film from which the electrolyte film base sheet has been separated, wherein the method further comprising a preliminary step of bonding either the second catalyst layer formed on the second catalyst layer base sheet or the second catalyst layer base sheet to a portion of the electrolyte film that has been fed prior to a position at which the bonding of the first catalyst layer starts in the first bonding step. |
