    摘要： A nanocomposite includes metal-carbon nanotubes and a sulfonated polysulfone. In the nanocomposite, the sulfonated polysulfone and the metal-carbon nanotubes have strong attraction therebetween due to π-π interactions or van der Waals interactions, and thus the nanocomposite has excellent ionic conductivity and mechanical properties. In addition, the nanocomposite includes a metal that can be used as a catalyst for an anode, and thus the reduction in power generation caused by methanol crossover can be minimized. Therefore, a nanocomposite electrolyte membrane prepared using the nanocomposite can minimize the reduction in power generation caused by the crossover of a polar organic fuel such as methanol. In a fuel cell employing the nanocomposite electrolyte membrane, when an aqueous methanol solution is used as a fuel, crossover of the methanol is more suppressed, and accordingly, the fuel cell has an improved operating efficiency and a longer lifetime.
