  • Polymer electrolyte membrane chemically bonded with ionic liquid and fuel cell using the same
    Patent number: 8853285
    Abstract: The present disclosure provides a polymer electrolyte membrane chemically bonded with an ionic liquid. More particularly, the present disclosure provides a polymer electrolyte membrane chemically bonded with an ionic liquid by reacting the ionic liquid with a novel polymer chain terminal. The polymer electrolyte membrane described herein has a high hydrogen ionic conductivity, even in a high-temperature and anhydrous environment. Additionally, the membrane displays electro-chemical and thermal stability. Moreover, the polymer electrolyte membrane may also be applied to a high-temperature and dry-out bio fuel cell.
