Abstract: An electrolyte membrane includes a nanocomposite ion complex that is a reaction product of a nanocomposite with a basic polymer. The nanocomposite includes a polymer having a sulfonic acid group and an unmodified clay. Either the unmodified clay has a layered structure and is dispersed in the polymer having the sulfonic acid group, and the polymer is intercalated between layers of the clay or the unmodified clay has an exfoliated structure and the exfoliated layers of the unmodified clay are dispersed in the polymer. The electrolyte membrane shows high mechanical strength, high ionic conductivity, and excellent methanol crossover impeding properties even when the degree of sulfonation of the polymer having the sulfonic acid group is high. When a methanol aqueous solution is used as a fuel, the fuel cell including the electrolyte membrane has a low methanol crossover, and thus, has a high operational efficiency and a long lifetime.

Abstract: A membrane electrode assembly for a fuel cell provides a current collector adjacent to an electrode catalyst layer. Since electrons passing between the current collector and the electrode catalyst layer do not pass through a diffusion layer or a supporting layer, the diffusion layer or supporting layer may be non-conductive. Thus, various materials that are hydrophilic, hydrophobic, porous, hydrous, or the like can be used for the diffusion layer and the supporting layer, thereby improving the performance of the fuel cell. In addition, manufacturing costs of the membrane electrode assembly can be decreased since the membrane electrode assembly can be manufactured quickly with low energy.
Abstract translation: 用于燃料电池的膜电极组件提供与电极催化剂层相邻的集电体。 由于在集电体和电极催化剂层之间通过的电子不通过扩散层或支撑层，所以扩散层或支撑层可以是不导电的。 因此，可以将各种亲水，疏水，多孔，含水等的材料用于扩散层和支撑层，从而提高燃料电池的性能。 此外，膜电极组件的制造成本可以降低，因为可以以低能量快速制造膜电极组件。
