Abstract

본 발명은 강도가 개선된 다공성 지지체, 그를 이용한 강화 복합전해질 막 및 그 막을 구비한 막-전극 어셈블리 및 연료전지에 관한 것이다. 본 발명의 다공성 지지체는 전기방사 이후, 열처리 수단 또는 가교제의 도입 에 의해 비약적으로 기계적 강도가 개선된 다공성 지지체로서, 전기방사에 적용되는 다양한 고분자 재질의 다공성 지지체를 제공할 수 있으며, 상기 다공성 지지체 내부에 수소이온 전도성 고분자가 함침되어 제조된 강화 복합전해질 막을 제공할 수 있다. 이에, 본 발명의 강화 복합전해질 막은 높은 기공도를 유지하면서도 기계적 강도, 전기화학적 특성 및 내구성이 개선되므로 이를 채용한 막-전극 어셈블리 및 연료전지의 성능을 향상시킬 수 있다.
