Problems solved by technology

[0005] However, at this time, the adsorption pores of the support are polluted by absorbing the catalyst particles separated from the catalyst layer arranged on the electrolyte membrane or the gas diffusion layer, and many adsorption pores may be clogged.
As a result, there is a problem of reduced production efficiency

Embodiment approach 2

[0115] Figure 14 and Figure 15 It is a side view and a sectional view for explaining Embodiment 2.

[0116] The second embodiment is basically different from the first embodiment in that the target of the laminated spacer 40 ( 45 ) is the gas diffusion layer 35 ( 36 ).

[0117] The gas diffusion layer 35 (36) is configured with a catalyst layer 32 (33), such as Figure 14 As shown, the flat portion 96 fixed to the mounting table 95 is transported by the transport device 80 so that the spacers 40 (45) are stacked on the outer peripheral edge 37 (38).

[0118] In this case, the liner 40 (45) is sucked and disposed on the groove portion 72 of the flat surface portion 70 of the support body 65 and conveyed, so that the liner 40 (45) is prevented from being wrinkled and the spacer 40 (45) is suppressed. The wrinkles are transferred to the outer peripheral edge 37 (38) of the gas diffusion layer 35 (36). The groove portion 72 is frame-shaped and does not absorb the gasket at t...

Abstract

[Problem] To provide a holding device that is for a fuel cell gasket and that can evince favorable production efficiency. [Solution] The holding device (60) for a fuel cell gasket is for laminating a frame-shaped gasket (40 (45)) to the outer rim (31) of a gas diffusion layer or an electrolyte membrane (30) at which a catalyst layer (32 (33)) is disposed and configuring a membrane electrode assembly of the fuel cell, wherein the holding device (60) has a support body (65) having a planar section (70) that suctions the gasket (40 (45)). The planar section (70) has a frame-shaped groove corresponding to the shape of the gasket (40 (45)), the groove is connected to an air aspiration unit (85), and the gasket (40 (45)) is suctioned by means of aspirating the air in the groove.

Description

technical field [0001] The invention relates to a holding device for a gasket for a fuel cell. Background technique [0002] A membrane electrode assembly (MEA: membrane electrode assembly) included in a unit cell of a fuel cell has an electrolyte membrane, a catalyst layer, a gas diffusion layer, and a frame-shaped gasket. The gasket is stacked on both surfaces of the electrolyte membrane, positioned so as to surround the catalyst layer, and has a function of preventing fuel gas and oxidant gas supplied to the catalyst layer from leaking to the outside. [0003] When the gasket is laminated on the electrolyte membrane or gas diffusion layer, the gasket is adsorbed on the support with a plurality of adsorption holes to prevent the gasket from wrinkling, and to suppress the diffusion of the wrinkles of the gasket to the electrolyte membrane or gas Layer transfer (for example, refer to Patent Document 1). [0004] Patent Document 1: (Japanese) Unexamined Patent Application P...
