Embodiment Construction

[0065] Such as figure 1 As shown in , the membrane / electrode assembly punching device 10 (hereinafter referred to as "MEA punching device 10") constituting the punching station is composed of the following components, namely: a lower die 14, on which a polymer electrolyte membrane 13a is placed (hereinafter written as "PEM13a"; as such, the PEM before punching is written as PEM13a to distinguish it from PEM13 after punching which will be discussed further later), the polymer electrolyte membrane 13a has a pressurized Carbon electrodes 11, 12 made of carbon paper fixed to its two sides; upper die 16 with a punching blade 15 for cutting off the edge of the PEM 13a (i.e. punching the PEM 13a); suction / clamping device 17, It serves as a pressing piece connected with the upper die 16 for sucking and clamping the carbon electrode 12 and the PEM 13a; and a cylinder device 18 for lowering the upper die 16 .

[0066] This lower die 14 is made up of following parts, namely: table part...

Abstract

A membrane / electrode assembly trimming apparatus ( 10 ) made up of a lower trimming die ( 14 ) on which a membrane / electrode assembly ( 65 ) is set, an upper trimming die ( 16 ) having a trimming blade ( 15 ) and a pressing member ( 17 ) which is ascend / descendably suspended from this upper trimming die and suction-holds a carbon electrode ( 12 ). A membrane / electrode assembly carrying apparatus ( 72 ) including a pressing member which suction-grips a carbon electrode and prevents it from slipping sideways is also disclosed. Because the certainty of the positioning, fixing and trimming of the membrane / electrode assembly at the time of trimming is raised and positional slipping of the trimmed membrane / electrode assembly during carrying can be prevented, the performance of the fuel cell improves.

Description

technical field [0001] The present invention relates generally to the manufacture of fuel cells, particularly fuel cell membrane / electrode assemblies punching systems, wherein the fuel cell membrane / electrode assemblies are positioned and secured for punching and prevent fuel cell membranes after punching. The position deviation during the conveying process of the sheet / electrode assembly, and the present invention relates to a fuel cell membrane / electrode assembly conveying device, by which the punching step and the conveying step can be smoothly connected, and the process from the conveying step can be realized smoothly Transfer to the stacking step. Background technique [0002] A fuel cell is a battery in which the reverse principle is used for electrolysis of water, whereby an electric current is obtained in the process of obtaining water by a reaction between hydrogen and oxygen. The terms fuel gas, air, and oxidizing gas are often used because, in general, fuel gas c...
