복합재는 플루오르화 중합체 및 금속 염의 나노입자를 포함한다. 금속 염은 용해도곱이 1 x 10-4 이하이다. 플루오르화 중합체는 플루오르화 중합체 골격 사슬 및 화학식 -SO2X (여기서, 각각의 X는 독립적으로 -NZH, -NZSO2(CF2)1-6SO2X', -NZ[SO2(CF2)dSO2NZ]1-10SO2(CF2)dSO2X', 또는 -OZ이고, Z는 독립적으로 수소, 알칼리 금속 양이온, 또는 4차 암모늄 양이온이고, X'는 독립적으로 -NZH 또는 -OZ이고, 각각의 d는 독립적으로 1 내지 6임)로 표시되는 복수의 기를 포함한다. 복합재를 포함하는 중합체 전해질 막, 전극, 및 막 전극 조립체가 또한 제공된다. A composite includes a fluorinated polymer and nanoparticles of a metal salt. The metal salt has a solubility product of not more than 1×10−4. The fluorinated polymer includes a fluorinated polymer backbone chain and a plurality of groups represented by formula -SO2X, in which each X is independently -NZH, -NZSO2(CF2)1-6SO2X′, -NZ[SO2(CF2)dSO2NZ]1-10SO2(CF2)dSO2X′ or -OZ, and Z is independently a hydrogen, an alkali-metal cation, or a quaternary ammonium cation, X′ is independently -NZH or -OZ, and each d is independently 1 to 6. A polymer electrolyte membrane, an electrode, and a membrane electrode assembly including the composite are also provided.
