Abstract
Provided are an ion conductive resin fiber, an ion conductive hybrid membrane, a membrane electrode assembly and a fuel cell. The ion conductive resin fiber comprises an inner layer including an ion conductive resin; and an outer layer including an ion conductive resin having larger EW than the ion conductive resin of the inner layer, and surrounding the inner layer. The ion conductive resin fiber and the ion conductive hybrid membrane are excellent in ion conductivity, polar solvent stability and dimensional stability under low humidity conditions. The fuel cell manufactured using the same has advantages of stable operation and management of a system at ease, removal or reduction of components related to water management, and even in case of low relative humidity, operation at high temperature of 80° C. or higher.
