Proton exchange membrane fuel cells (PEMFCs)
have attracted much attention as a clean energy
source because of their high energy density and efficiency
for various applications such as electric
vehicles, portable electronics, and residential power
generation.1–6 The polymer electrolyte membrane
(PEM), which acts as an electrolyte to transport protons
from the anode to the cathode, is one of the key
components of polymer electrolyte membrane fuel
cells.7 A series of perfluorosulfonate ionomers, such
as Nafion, are the most widely used proton
exchange membranes in direct methanol fuel cells,
because of their high proton conductivity, excellent
chemical and physical properties. However, the high
cost, low operation temperature and high fuel crossover
as well as other problems have limited their
practical application in fuel cells.8–11 Therefore, it is
strongly desired to develop new proton exchange
membrane materials with lower cost and high
performance.

Answer 1

作为一种清洁能源，质子交换膜燃料电池（PEMFCs）引起了广泛关注，它们在不同的应用上（如：电动汽车、便携式电子产品和住宅发电）都具有很高的能量密度和效率。1-6聚电解质膜是聚电解质膜燃料电池的关键组分，它起到了电解液的作用，将质子从阳极运送到阴极。7一系列的全氟磺酸离子（如全氟磺酸），具有高质子导电率、优秀的化学和物理特性，是直接甲醇燃料电池中使用最广泛的质子交换膜。然而，高投入、低运行温度和高燃料交叉以及其他问题限制了它们在燃料电池中的实际应用。8-11因此，我们强烈希望开发一种新的低投入、高性能的质子交换膜材料。
