US 8,771,902 B2 · Manufacture of fuel cell

Abstract

A fuel cell is manufactured using a polymer electrolyte membrane (1). A catalyst layer (12) is formed at fixed intervals on the surface of the strip-form polymer electrolyte membrane (1) in the lengthwise direction thereof, and conveyance holes (10) are formed in series at fixed intervals on the two side portions thereof. By rotating a conveyance roller (32) comprising on its outer periphery projections which engage with the holes (10), the polymer electrolyte membrane (1) is fed from a reel (9). A GDL (6) and a separator (7) are adhered to the fed polymer electrolyte membrane (1) at a predetermined processing timing based on the rotation speed of the conveyance roller (32), and thus the fuel cell is manufactured efficiently while the GDL (6) and separator (7) are laminated onto the catalyst layer (12) accurately.

Dependent claims

A manufacturing method for a fuel cell formed by laminating a polymer electrolyte membrane and a separator alternately, comprising:

(1) a process of supplying a film-form polymer electrolyte membrane from a side of a first separator, which is held in a predetermined position, to a position facing the first separator in parallel with the first separator, then;
(2) a process of supplying a second separator and a cutter to an opposite side of the polymer electrolyte membrane, which faces the first separator, to the first separator;
and, then,
(3) a process of displacing the second separator and the cutter toward the first separator such that the polymer electrolyte membrane is sandwiched together with and between the first separator and the second separator and the polymer electrolyte membrane is cut into a predetermined shape and dimension at the same time that the first separator and second separate are cut into the same predetermined shape and dimension.
