摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a fuel cell capable of suppressing lowering of electron conductivity between a catalyst layer and a GDL in a fuel cell in which one end of a CNT is connected to an electrolyte membrane and the other end is connected to a GDL.SOLUTION: In a GDL bonding process, first, a GDL is arranged so as to contact with an outer surface of a CNT catalyst layer. In this case, the CNT catalyst layer is held at a temperature Twhich is lower than a thermosoftening temperature of an ionomer constituting such CNT catalyst layer, and the GDL is preheated at a temperature Twhich is higher than the thermosoftening temperature. In such arrangement, as a figure 2 (B) shows, a thermal gradient is generated between yand yaround a contact interface between the GDL and the CNT catalyst layer. Therefore, the CNT catalyst layer side between yand yof the figure (B) can be heated, and the ionomer between yand ycan be selectively softened. If a pressure is applied between the GDL and the CNT electrode layer in this state, an end of the exposed vertically-aligned CNT and the GDL can be directly connected.
摘要翻译：解决问题：为了提供能够抑制CNT的一端与电解质膜连接的燃料电池中的催化剂层与GDL之间的电子传导性降低的燃料电池的制造方法，另一端连接到GDL。解决方案：在GDL接合工艺中，首先，将GDL布置成与CNT催化剂层的外表面接触。在这种情况下，CNT催化剂层保持在低于构成这种CNT催化剂层的离聚物的热软化温度的温度T 1 ，并且GDL在温度T 2 ，高于热软化温度。在这种布置中，如图2（B）所示，在y 2 和y 1 之间产生热梯度 GDL和CNT催化剂层之间的接触界面。因此，可以加热图（B）的y 4 和y 1 之间的CNT催化剂层侧，并且离聚物可以选择性地软化y 4 和y 3 之间。如果在该状态下在GDL和CNT电极层之间施加压力，则可以直接连接暴露的垂直排列的CNT和GDL的一端。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a membrane electrode assembly that can enhance yield of a catalyst to be carried on a CNT.SOLUTION: The membrane electrode assembly 10 can be manufactured through steps of: (i) manufacturing the CNT; (ii) transferring it on a transfer base; (iii) applying the catalyst; (iv) dripping ionomer dispersion liquid; (v) drying; and (vi) performing a thermal transfer. A desired size of CNT 14 can be grown through (i) the step of manufacturing the CNT. However, a short poor growth CNT is formed simultaneously when the CNT is actually manufactured, so, this step is performed before the catalyst being applied on the CNT. Therefore, the catalyst can be applied in (iii) the step of applying the catalyst after removing the short poor growth CNT.
