有”锂”行天下 | 燃料电池的未来：聚合物电解质膜燃料电池的奥秘

来源：珀金埃尔默企业管理(上海)有限公司分类：政策 2024-01-05 10:16:21 13阅读次数

你知道吗？燃料电池，这个看似普通的名字，其实隐藏着巨大的能量和无限的可能。它是将化学能直接转换成电能的装置，既环保又高效，被视为未来能源的重要形式。而在这其中，聚合物电解质膜燃料电池（PEMFC）更是独领风骚。

聚合物电解质膜燃料电池，顾名思义，它的核心在于那层薄薄的聚合物膜。这层膜起着电解质的角色，能快速传输氢离子，使化学能高效转化为电能。与此同时，这种电池的重量轻、体积小，启动迅速，寿命长，使其在各种应用场景中都表现出色。

而在这其中，膜电极的制备尤为关键。它由质子交换膜、催化层以及气体扩散层组成，每一层都有其独特的功能和重要性。而为了确保其质量和性能，我们采用了热重分析这一先进技术。

热重分析是一种在加热过程中测量物质质量变化的强大工具。通过精确的温度控制和重量测量，我们可以深入了解样品的成分和性能。这对于我们理解碳布的热处理工艺、控制催化剂油墨的配方等都至关重要。
