Approaches to Improvement in the Stability of Polymer Electrolyte Membranes |
| 초록 |
Polymer electrolyte membrane fuel cell (PEMFC) is an eco-friend energy device. It has high energy efficiency and wide power ranges. Polymer electrolyte membrane (PEM) is one of key components in PEMFC. Electrochemical performance of PEM has been improved, whereas long-term durability of PEM needs to be further improved. There are two kinds of stability issues in PEM. One is chemical stability and the other is mechanical stability. In this study, we investigated the effect of radical scavengers on the chemical stability of PEM, while the mechanical stability of PEM was improved by fabricating reinforced composite membrane. Radical scavengers improved chemical stability of both perfluorosulfonic acid polymers and hydrocarbon-based polymers. In addition, reinforced composite membranes had better mechanical properties than dense membranes. |
