技术领域
本发明属于高分子材料技术领域,涉及一种燃料电池部件,具体涉及一种低温质子交换膜及其制备方法。

质子交换膜是质子交换膜燃料电池的“心脏”部件,其性能的好坏直接影响质子交换膜燃料电池的正常工作、寿命、能量转化率,在质子交换膜燃料电池中起着阻隔燃料和传递质子的双重作用。
目前,应用最多的质子交换膜为以杜邦公司生产的以Nafion膜为代表的全氟磺酸聚合物膜,这类质子交换膜具有极好的热力学和化学稳定性,且在湿态条件下具有较高的质子传导率,然而,它们存在高成本、高甲醇渗透等缺点,这些缺点阻碍了这类质子交换膜的进一步应用。作为改进,现有技术中报道了一些改性Nafion膜和新型结构聚合物膜,这类膜或多或少存在湿态条件下溶胀度太大,机械性能得不到保障,吸水保水性能弱,成本仍然昂贵的缺点。
因此,市场上亟需一种能替代Nafion膜,价格低廉,质子传导率高、机械性能好、甲醇渗透率低、吸水保水性能优异的低温质子交换膜。

其中,所述四[4-(4'-羧基苯基)苯基]乙烯、二烯丙基二硫、羧基化富勒烯、乳化剂、光引发剂的质量比为3:(1-2):(0.3-0.5):(0.03-0.05):(0.03-0.05);
所述乳化剂选自十二烷基苯磺酸钠、聚氧丙烯聚乙烯甘油醚、壬基酚聚氧乙烯醚中的一种或几种;
所述引发剂选自安息香、安息香双甲醚、安息香乙醚、安息香异丙醚、安息香丁醚中的一种或几种;
所述惰性气体选自氖气、氦气、氩气中的一种或几种。
一种低温质子交换膜,采用所述一种低温质子交换膜的制备方法制备得到;
一种质子交换膜燃料电池,采用所述一种低温质子交换膜作为聚合物电解质膜。
采用上述技术方案所产生的有益效果在于:
1)本发明提供的一种低温质子交换膜的制备方法简单易行,对设备要求不高,原料易得,价格低廉。
2)本发明提供的一种低温质子交换膜,基体采用含多芳香环结构的聚合型单体与含有硫基的单体聚合形成,且设计有交联结构,使得膜具有较好的机械力学性能、化学稳定性和热稳定性。

对比例
市售Nafion膜
对上述实施例1-4以及对比例所得样品进行相关性能测试,测试结果如表1所示,测试方法如下,
(1)拉伸强度测试:按照GB/T 1040-2006《塑料拉伸性能试验方法》进行测试;
(2)质子电导率:制备的质子交换膜的阻抗,是采用两电极交流阻抗法在电化学工作站(Zahner IM6EX)上测得的,测试频率为1Hz~1MHz。电导率测试是在装满去离子水的容器里测定的,这是为了保证膜的相对湿度为100%,并控制温度在30℃。在这一温度点测试之前,样品在此温度下保持恒温30min,电导率根据下列公式计算:
其中,σ为质子电导率(S cm-1),l为两电极之间的距离(cm),R为所测样品的交流阻抗,S为膜的横截面面积。
(3)氧化稳定性:制备的质子交换膜的氧化稳定性是通过将膜浸泡在70℃的Fenton试剂(含有4ppm Fe2+的3%的双氧水溶液)中20小时,称量并计算膜的重量保留率来衡量的。计算公式为:保留率=(浸泡后膜重量-浸泡前膜重量)/浸泡前膜重量×100%。
(4)溶胀度、吸水率:膜样品在水中的溶胀度是通过比较膜在室温下浸泡24小时后表面积的变化来计算得到的,计算公式如下:溶胀度=(浸泡后膜表面积-浸泡前膜表面积)/浸泡前膜表面积×100%;膜样品在水中的吸水率是通过比较膜在室温下浸泡24小时后重量的变化来计算得到的,计算公式如下:吸水率=(浸泡后膜重量-浸泡前膜重量)/浸泡前膜重量×100%。
表1实施例和对比例样品性能
从表1可以看出,本发明公开的低温质子交换膜具有较好的机械性能和化学稳定性,并且质子传导率率也比市售质子交换膜高,溶胀度低,吸水率高,符合质子交换膜燃料电池使用要求。
以上所述,仅为本发明的较佳实施例而已,并非对本发明作任何形式上的限制;凡本行业的普通技术人员均可按说明书所示和以上所述而顺畅地实施本发明;但是,凡熟悉本专业的技术人员在不脱离本发明技术方案范围内,可利用以上所揭示的技术内容而作出的些许更动、修饰与演变的等同变化,均为本发明的等效实施例;同时,凡依据本发明的实质技术对以上实施例所作的任何等同变化的更动、修饰与演变等,均仍属于本发明的技术方案的保护范围之内。
