(EN) Method of manufacturing seal-integrated type membrane electrode assembly
(ZH) 制造密封一体式膜电极组件的方法
Abrégé
(EN)
In a process of manufacturing a membrane electrode assembly, seal-material flow holes (62a, 62b) in the form of through-holes are formed, separately from manifold holes (16a - 16f), in the membrane electrode assembly prior to injection molding. When the membrane electrode assembly is placed in a mold for injection molding, the seal-material flow hole (62a) is located in a cavity (44a). When a seal material is supplied from a supply port (42) formed at a location where the manifold hole (16a) is formed, the seal material that flows toward the upper die (40a) passes the seal-material flow hole (62a) in the cavity (44a), and then flows toward the lower die (40b), so as to reduce the unevenness between the amounts of supply of the seal material to the upper die (40a) and the lower die (40b).

(ZH)

在制造膜电极组件的过程中,在注塑成型之前,呈通孔形式的密封材料流入孔(62a、62b)与歧管孔(16a-16f)分开地形成于膜电极组件中。当膜电极组件置于用于注塑成型的模具中时,密封材料流入孔(62a)置于腔(44a)中。当密封材料从供应口(42)——该供应口形成于歧管孔(16a)的形成位置处——供应时,流向上模(40a)的密封材料经过腔(44a)中的密封材料流入孔(62a),并然后流向下模(40b),从而减少了供应到上模(40a)和下模(40b)的密封材料的量之间的不均匀度。
