Description

气体扩散层片材的加工装置
技术领域
本发明涉及燃料电池等中使用的气体扩散层片材的加工装置。
背景技术
以往，在燃料电池中，例如在电解质膜的两膜面接合具有用于促进燃料电池反应的催化剂的阳极及阴极的电极催化剂层来构成膜电极接合体。膜电极接合体通过如下方式制造：长条状的电解质膜片材与形成有电极催化剂层的支承片材重叠，从而电极催化剂层接合于电解质膜面，并由转印辊进行转印。在形成有电解质膜片材的背板上相连有虚设片材，在该相连的部位的表背面粘接有带(例如、专利文献1)。
在先技术文献
专利文献
专利文献1：日本国专利第5979100号公报
发明要解决的课题
在上述公报记载的形成有电解质膜片材的背板上通过带而相连有虚设片材，但未考虑带对于干燥炉的耐热性。因此，存在如下问题：带在干燥炉中无法保证接合强度而分离，或者给成为产品的电解质膜片材带来不良影响，或者在电解质膜片材中产生褶皱。
发明内容
本发明的目的在于，提供在进行干燥炉这样的加热加工的加工炉中不给产品带来不良影响、不容易在产品产生褶皱的气体扩散层片材的加工装置。
用于解决课题的方案
为了达到上述目的，本发明提供一种气体扩散层片材的加工装置(例如后述的气体扩散层片材的加工装置1)，其具备：第一辊(例如后述的放出用辊10)，其卷缠有气体扩散层片材(例如后述的碳纸CP)，该气体扩散层片材为导电性的多孔质体；第二辊(例如后述的卷绕用辊20)，其对卷缠到所述第一辊后放出的所述气体扩散层片材进行卷绕；以及加工炉(例如后述的干燥炉30)，其对从所述第一辊放出且卷绕于所述第二辊之前的所述气体扩散层片材进行加热加工，其特征在于，所述气体扩散层片材的加工装置具备耐热性引导件(例如后述的耐热性引导件LE)，该耐热性引导件至少具有通过所述加工炉并到达所述第二辊的长度，且向所述第二辊卷绕，所述耐热性引导件通过热固化性树脂(例如后述的粘接剂AD)浸渍于气体扩散层片材来接合于气体扩散层片材。
根据本发明，通过在气体扩散层片材上浸渍热固化性树脂而接合于耐热性引导件，能够形成如下结构：在该热固化性树脂的部分确保耐热性，且保证接合强度，并且褶皱少。这样，能够确保接合部分处的耐热性，因此能够防止热固化性树脂在加工炉的内部给气体扩散层片材带来不良影响。
另外，通过热固化性树脂将耐热性引导件与气体扩散层片材接合，因此在热固化性树脂所包含的溶剂气化之后，能够使气化了的溶剂从多孔质的碳纸放出。因此，能够抑制在使热固化性树脂干燥之后进行冷却时在碳纸产生褶皱的情况。
并且，与所述耐热性引导件的对所述气体扩散层片材进行接合的部分相邻的所述耐热性引导件的部分具有褶皱释放部(例如后述的切口CU)，该褶皱释放部使在所述气体扩散层片材产生的褶皱展开。
并且，所述褶皱释放部由在所述耐热性引导件的部分所形成的切口(例如后述的切口CU)构成。
因此，在耐热性引导件的切口处，能够可靠地抑制在使热固化性树脂干燥之后进行冷却时在气体扩散层片材产生褶皱的情况。
并且，热固化性树脂在耐热性引导件的长度方向上的端部处从耐热性引导件的宽度方向一端部附近到另一端部附近而沿着宽度方向呈一条线形状涂布，从而接合于碳纸。因此，在热固化性树脂所包含的溶剂气化之后，能够容易使气化了的溶剂从多孔质的碳纸放出。另外，在使热固化性树脂干燥之后进行冷却时，不容易在气体扩散层片材产生褶皱，且能够可靠地进行接合。
另外，在气体扩散层片材的长度方向上的端部处，使热固化性树脂浸渍，在气体扩散层片材位于耐热性引导件之上的状态下，使热固化性树脂加热固化来进行接合，由此在热固化性树脂所包含的溶剂气化之后，能够使气化了的溶剂从多孔质的气体扩散层片材较佳地放出。因此，能够进一步抑制在使热固化性树脂干燥之后进行冷却时在气体扩散层片材产生褶皱的情况。
发明效果
根据本发明，能够提供在进行加热化加工的加工炉中不带来不良影响、不容易在产品产生褶皱的气体扩散层片材的加工装置。

具体实施方式
以下，参照附图来说明本发明的实施方式。图1是表示气体扩散层片材的加工装置1的简要图。
如图1所示，气体扩散层片材的加工装置1是如下装置：用于针对将气体扩散层片材切出为规定尺寸而构成燃料电池的气体扩散层的碳纸CP(气体扩散层片材)进行形成电极、防水层等的涂覆，从而形成电解质膜等，所述加工装置1具备放出用辊10、卷绕用辊20、作为进行加热加工的加工炉的干燥炉30、以及模头40。
在放出用辊10预先卷绕有碳纸CP，放出用辊10朝向卷绕用辊20放出碳纸CP。模头40对从放出用辊10放出的碳纸CP进行形成电极、气体扩散层、防水层的涂覆。干燥炉30的内部例如设为400℃左右的高温的气氛，由模头40进行了电极、气体扩散层、防水层的涂覆的碳纸CP通过干燥炉30的内部而被进行加热加工并被干燥。卷绕用辊20卷绕形成有电极、防水层及气体扩散层的碳纸CP。
在从放出用辊10放出的碳纸CP的前端部接合耐热性引导件LE。耐热性引导件LE由具有与碳纸CP的宽度相同的宽度的聚酰亚胺材料的树脂膜构成。耐热性引导件LE的一端部固定于卷绕用辊20，且向卷绕用辊20卷绕。
耐热性引导件LE具有通过模头40及干燥炉30而从放出用辊10到卷绕用辊20为止的长度，耐热性引导件LE的另一端部通过由称作所谓的清漆的聚酰亚胺系的热固化性树脂构成的粘接剂AD(参照图2)而接合于从放出用辊10放出的碳纸CP的前端部。耐热性引导件的长度至少具有通过干燥炉30并到达卷绕用辊20的长度即可。
在碳纸CP的后端部，也通过由上述的聚酰亚胺系的热固化性树脂构成的粘接剂AD(参照图2)而接合同样的耐热性引导件。该耐热性引导件至少具有通过干燥炉30并到达放出用辊10为止的长度，优选具有放出用辊10与卷绕用辊20之间的长度。
因此，在耐热性引导件LE通过模头40、干燥炉30而被卷绕用辊20卷绕之后，碳纸CP也同样地通过模头40及干燥炉30而被卷绕用辊20卷绕。
图2是表示气体扩散层片材的加工装置1中的碳纸CP与耐热性引导件LE的接合部分的简要图。
耐热性引导件LE的另一端部与碳纸CP的前端部在碳纸CP位于上方的状态下经由粘接剂AD接合于耐热性引导件LE。更具体而言，耐热性引导件LE的另一端部与碳纸CP的前端部的接合通过以下方式进行。
首先，如图3所示，在耐热性引导件LE的另一端部的上表面涂布粘接剂AD。粘接剂AD的涂布在耐热性引导件LE的另一端部的上表面上呈沿着耐热性引导件LE的宽度方向的一条线形状、更详细而言如图2所示那样呈长圆形状进行。接着，如图4所示，从涂布有粘接剂AD的耐热性引导件LE的上方贴附碳纸CP的前端部，从而在耐热性引导件LE的另一端部粘贴碳纸CP的前端部。由此，如图2所示那样呈长圆形状涂布的粘接剂AD扩展，使粘接剂AD浸渍于碳纸CP的前端部。
图3是表示气体扩散层片材的加工装置1中的耐热性引导件LE上涂布有粘接剂AD的情形的侧方截面简要图。图4是表示气体扩散层片材的加工装置1中的耐热性引导件LE经由粘接剂AD而接合有碳纸CP的情形的侧方截面简要图。
并且，如图5所示，使用加热器70来对这样接合的部分进行加热，从而使其干燥并固化。由此，使粘接剂AD所包含的溶剂气化而从多孔质的碳纸CP放出。另外，在该加热接合时，使耐热性引导件LE及碳纸CP自由膨胀。通过以上那样操作，从而耐热性引导件LE的另一端部与碳纸CP的前端部接合。
图5是表示气体扩散层片材的加工装置1中的使在耐热性引导件LE接合碳纸CP的粘接剂AD固化的情形的侧方截面简要图。
根据本实施方式，起到以下的效果。
在本实施方式中，气体扩散层片材的加工装置1具备：作为第一辊的放出用辊10，其卷缠有碳纸CP；作为第二辊的卷绕用辊20，其对卷缠到放出用辊10后放出的碳纸CP进行卷绕；以及作为加工炉的干燥炉30，其对从放出用辊10放出且卷绕于卷绕用辊20之前的碳纸CP进行加热加工。
并且，所述加工装置1具备耐热性引导件LE，该耐热性引导件LE具有通过干燥炉30并到达卷绕用辊20为止的长度，且向卷绕用辊20卷绕，耐热性引导件LE通过由热固化性树脂构成的粘接剂AD浸渍于气体扩散层片材来接合于气体扩散层片材。
由此，通过由热固化性树脂构成的粘接剂AD浸渍于碳纸CP，碳纸CP接合于耐热性引导件LE，从而能够形成如下结构：在该接合部分确保400℃左右的耐热性，且保证接合的耐久性，并且褶皱少。这样，接合部分处的耐热性得以确保，因此能够防止粘接剂AD在干燥炉30的内部给碳纸CP带来不良影响。
另外，通过粘接剂AD将耐热性引导件LE与碳纸CP接合，因此粘接剂AD所包含的溶剂气化之后，能够从多孔质的碳纸CP放出。因此，能够抑制在使粘接剂AD干燥之后进行冷却时在碳纸CP产生褶皱的情况。
并且，由热固化性树脂构成的粘接剂AD在耐热性引导件LE的长度方向上的端部处从耐热性引导件LE的宽度方向一端部附近到另一端部附近为止而沿着宽度方向呈一条线形状涂布并接合于碳纸CP。因此，在使粘接剂AD干燥之后进行冷却时，热固化性树脂所包含的溶剂气化之后，能够容易使气化了的溶剂从多孔质的碳纸放出，不容易在碳纸CP产生褶皱，且能够可靠地接合。
本发明并不限定于上述实施方式，在能够达到本发明的目的的范围内的变形、改良等包含于本发明中。
例如，耐热性引导件LE的部分且是与耐热性引导件LE的对碳纸CP进行接合的部分相邻的部分也可以具有褶皱释放部，该褶皱释放部使在碳纸CP产生的褶皱展开。
具体而言，例如，褶皱释放部由在耐热性引导件LE的部分形成的切口CU构成。如图6所示，对于切口CU，在耐热性引导件LE的另一端部与碳纸CP的前端部的接合部分处从耐热性引导件LE的另一端部与碳纸CP的前端部重叠的部分的缘部起，朝向耐热性引导件LE的一端部而平行地形成有多根15cm～20cm的长度的切口CU。耐热性引导件LE的宽度方向上的切口CU的间隔为8cm左右。
这样，在耐热性引导件LE的部分且与耐热性引导件LE的对碳纸CP进行接合的部分相邻的部分具有褶皱释放部，该褶皱释放部使在碳纸CP产生的褶皱展开。并且，褶皱释放部由在耐热性引导件LE的部分形成的切口CU构成。因此，在使粘接剂AD干燥之后进行冷却时，能够利用耐热性引导件LE的切口CU来吸收在碳纸CP产生的褶皱，能够可靠地抑制在碳纸CP产生褶皱的情况。
图6是表示气体扩散层片材的加工装置1中的碳纸CP与耐热性引导件LE的接合部分的俯视简要图。
另外，切口CU不限定于上述形状。
另外，作为气体扩散层片材，不限于碳纸，只要是导电性的多孔质材料即可，也能够优选利用导电性树脂、导电材料和树脂的组合物、金属纤维体等。
而且，第一辊、第二辊、加工炉、耐热性引导件、褶皱释放部等各部分的结构不限定于本实施方式中的放出用辊10、卷绕用辊20、干燥炉30、耐热性引导件LE、切口CU等各部分的结构。例如，进行加热加工的加工炉也可以代替干燥炉30而使用烧成炉。另外，例如，粘接剂AD不限定于呈一条线形状涂布，例如也可以呈间歇线状涂布。
