一种新型的质子传导聚合物电解质膜，磺化聚酰亚胺具有脂肪族部分（SPI-5），进行了长期的燃料电池运行。SPI-5膜的高耐久性通过在80°C下5000小时的单细胞测试来证实。尽管如此，SPI-5膜在细胞操作后变得脆弱。通过对膜的厚度、离子交换容量、分子量和核磁共振谱的变化进行研究，认为磺化聚酰亚胺膜最可能的降解方式是酰亚胺键的水解，同时也可能参与氧化降解。
A novel proton conducting polymer electrolyte membrane, sulfonated polyimide having aliphatic moieties (SPI-5), was subjected to long-term fuel cell operation. High durability of the SPI-5 membrane was confirmed by single-cell testings at 80°C for 5000 h. Still, the SPI-5 membrane turned out to be fragile after the cell operation. Through the investigation of the changes in thickness, ion exchange capacity, molecular weight, and NMR spectra, it was concluded that the most probable degradation mode of the sulfonated polyimide membrane should be the hydrolysis of imide linkages, while oxidative degradation is also likely to be involved.
