Abstract
本发明涉及一种碳纤维基础上的气体扩散层(Gas Diffusion Layer -GDL)，所述气体扩散层用于聚合物-电解质-膜片(PEM)燃料电池(BZ)中，其具有结构化亲水物，其中，具有亲水特性的材料从平均畴尺寸0.5至80μm、在气体扩散层内存在作为亲水芯条的金属氧化物的组中选取。
Description
技术领域
本发明涉及一种碳纤维基础上的气体扩散层(Gas Diffusion Layer-GDL)，该气体扩散层具有结构化亲水物，其在聚合物-电解质-膜片(PEM)燃料电池(BZ)中使用。
背景技术
燃料电池是高效能源，其中燃料(典型的是富含氢的气体)和氧化剂(典型的是空气氧)在PEM两个主面的催化剂层上电化学转换成水。通过电化学反应产生电能和反应物在形成水的情况下产生反应。PEM在此方面承担半块电池之间的质子传输，其中，电子通过电极和外部电路用于完成电功。这种类型的燃料电池的主要问题是，膜片和相邻的催化剂层必要的湿度保持以及所形成的水的排出之间的平衡，否则水充满GDL孔、阻碍气体传输以及降低输出功率。湿度水平受到一系列因素的影响和控制。阳极和阴极反应气体的增湿通常用于调整必要的湿度水平。工作条件(电池温度、气体压力和气体化学计量)是影响膜片和GDL水分的其他影响值。最后燃料电池工作的功率范围也对电池内水含量的平衡产生重要影响。高电流密度下的运行导致产生高的水含量，这种水含量占主导地位并必须这样被引导，使得以可靠和无干扰的方式实现最佳状态。
文献DE 102 60 501A1公开了一种具有用于控制水横向扩散的层的气体扩散电极。在此方面，气体扩散电极的微孔的GDL与大孔的GDL之间具有由亲水纤维，特别是亲水碳纤维组成的水横向扩散层。
文献WO 2007/139940A2公开了一种用于PEM燃料电池的热量和水管理装置。该装置由热和导电的亲水的热量和水输送元件组成，该热量和水输送元件从电池的内部向电池的外部延伸并设置在GDL与电流输出器之间。传输元件由氮化硼、氮化铝、铜-、铝-、镍-合金、石墨、膨胀石墨、石墨布、石墨纸、铝泡沫、不锈钢泡沫、镍泡沫、聚乙烯醇泡沫、玻璃微纤维、粗纺毛织物、棉纸、棉布、聚氨酯泡沫、纤维素醋酸酯、聚乙烯吡咯烷酮或者聚丙烯酰胺组成。
发明内容
本发明的目的在于，提供一种GDL，该GDL通过其构造可以保证有效的水管理并因此在持续的高功率输出情况下以简单方式控制和运行燃料电池。
依据本发明，依据分类提出的GDL的目的利用权利要求1的特征得以实现。其他具有优点的构成在权利要求2至10中予以说明。本发明还涉及一种按权利要求11至14所述用于制造依据本发明的GDL的方法以及按权利要求15所述GDL的应用。
将侧向预先规定的路径置入GDL内，液态水应在这些路径上聚集，以便可以沿该路径被传输。亲水芯条上的区域应有针对性地吸出液态水，以便使直接相邻的孔可靠开放用于气体传输。
这些路径可以以如下方式被置入
·将亲水纤维加入微孔层(MPL)内，
·将亲水纤维置入到MPL/催化剂交界层上，
·将纤维置入到衬底/MPL交界层上，
·置入具有微米/纳米尺度的亲水物质的印制图形。
作为亲水纤维使用无机纤维如氧化铝或者Al2O3-SiO2(“铝硅酸盐”)的混合纤维。这些纤维被切割或者作为磨碎的纤维来获得。作为其他亲水物质可以考虑基于SiO2(热解硅酸，fumed silica)、TiO2、Al2O3或者B2O3的微米或者纳米尺度的颗粒。
亲水芯条的侧向和垂直定向在此方面是重要的：在小和中等负载范围内，优选这些范围在流动区的接片上有助于PEMBZ的功率。优选那里存在液态水形式的反应产物。接片上形成的液态水必须横向于接片排入通道内并避免GDL的大空间注水泛滥。因此必须是芯条定向理想地与流动区几何形状相一致。为尽可能通用地构成这一点，提出一种蜂巢状结构，蜂巢状结构具有流动区结构数量级的蜂房宽度，作为选择也适用类似的简单多角形结构。由此使液态水从反应区的流出变得容易并同时为到反应位置的必要的气体传输创造自由空间。
液态水的传输行程多样构成并需要在三个空间方向上。需要指出的是，液态水聚集在催化剂-MPL分界面上。这种液态水以蒸汽形式通过MPL并以液态形式重新聚集在衬底内。这种以蒸汽形式通过MPL(蒸发和再凝结)是引起效率和动力损失的附加过程。液态水沿亲水畴
通过MPL传输(在Z方向上)可以产生功率优点。
具体实施方式
实施例1
将型号Sigracet
GDL 25BA的碳纤维纸(SGL Technologies GmbH，Meitingen)利用涂层膏在实验室刮板上涂层(层厚30-50μm)并随后在350℃烧结10分钟。向涂层膏(由77％的乙炔炭黑、23％的聚四氟乙烯(PTFE)和有机胶结物料组成)添加不同量的预磨碎的氧化铝纤维(事先在水中分散)。
样品A(MUSTER A)：与膏的固体含量相关0.16％的氧化铝纤维
样品B(MUSTER B)：与膏的固体含量相关0.29％的氧化铝纤维
样品C(MUSTER C)：与膏的固体含量相关0.67％的氧化铝纤维
涂层内少量的无机纤维就已经使得表面产生明显的亲水性(无纤维的表面由于层内的PTFE部分而明显疏水)。但电阻也随着纤维比例的增加而上升。
实施例2
氧化铝纤维的水状分散物(0.01至0.05％，添加粘结剂/分散剂)在处于筛网(例如成页机/造纸机)上无涂层的GDL衬底上真空脱水。由此在GDL上产生在x-y方向上定向的纤维沉积物。干燥之后GDL具有微孔层。
