质子膜燃料电池用含氟离子交换膜的研制
和开发
Proton exchange membrane fuel cells (PEMFCs) are a promising technology for clean energy generation. However, the development and fabrication of fluorinated ion exchange membranes remain an ongoing challenge in this field.
质子膜燃料电池(PEMFCs)是清洁能源发电的一项有前景的技术。

然而,含氟离子交换膜的研制和制备仍然是这个领域面临的持续挑战。

Fluorinated ion exchange membranes play a crucial role in PEMFCs by facilitating proton transport while blocking the crossover of reactants and products. These membranes need to possess specific properties such as high proton conductivity, excellent chemical stability, low methanol permeability, and good mechanical strength.
含氟离子交换膜在质子膜燃料电池中起着至关重要的作用,它们在促进质子传输的同时阻止了反应物和产物的混合。

这些膜需要具备高的质子导电性、良好的化学稳定性、低甲醇渗透性以及较好的机
械强度等特殊属性。

To develop these membranes, researchers have been exploring different materials and approaches. One approach involves the modification of commercial perfluorosulfonic acid (PFSA) membranes like Nafion. By incorporating functional groups
or introducing nanostructures onto the PFSA backbone, researchers aim to improve various performance parameters
of the resulting membrane.
为了开发这些膜,研究人员一直在探索不同的材料和方法。

其中一
种方法涉及到对商业化的全氟磺酸(PFSA)膜(如Nafion)进行改性。

通过在PFSA骨架上引入功能基团或纳米结构,研究人员目的是
提高膜的各种性能参数。

Another approach involves the synthesis of entirely new materials for ion exchange membranes, such as perfluorophosphonic acid-based polymers or hydrocarbon-
based polymers. These materials offer the advantage of
being potentially less expensive and more readily available than PFSA membranes. However, they still face challenges in achieving comparable proton conductivity and stability
properties.
另一种方法涉及到合成全新的离子交换膜材料,如基于全氟膦酸或碳氢化合物为基础的聚合物。

这些材料具有潜在的成本较低、更易得到的优点,相比PFSA膜来说。

然而,它们在实现可比质子导电性和稳定性方面仍面临挑战。

In addition to material development, researchers are also focusing on improving the fabrication processes of fluorinated ion exchange membranes. Enhancements in techniques such as electrospinning, casting, and coating deposition offer opportunities to optimize membrane morphology and enhance performance characteristics.
除了材料开发外,研究人员还致力于改进含氟离子交换膜的制备工艺。

像电纺丝、浇铸和涂覆沉积等技术的改进,为优化膜的形态学和提高性能特性提供了机会。

In conclusion, the development and fabrication of fluorinated ion exchange membranes for PEMFCs continue to be an active field of research. Scientists are exploring various materials and approaches to improve the performance
characteristics of these membranes, aiming for higher proton conductivity, improved chemical stability, lower methanol permeability, and better mechanical strength.
总之,质子膜燃料电池用含氟离子交换膜的研制和制备仍然是一个活跃的研究领域。

科学家们正在探索各种材料和方法,以改善这些膜的性能特性,力争实现更高的质子导电性、改善化学稳定性、降低甲醇渗透率和提高机械强度。
