The present invention relates to a separator membrane for a fuel cell, a method for preparing same, and a fuel cell electrode assembly. A separator membrane for a fuel cell comprises: a support whichis formed by means of accumulation of fibers, containing 20-50 wt% of fiber-forming polymers and 50-80 wt% of heat-resistant polymers, and has a plurality of pores; and an ion exchange resin which fills the plurality of pores of the support. 本发明涉及燃料电池用分离膜、其制备方法及燃料电池电极组件，燃料电池用分离膜包括：支撑体，由包含20～50重量百分比的纤维成型性高分子及50～80重量百分比的耐热性高分子的纤维累积而成，具有多个气孔；以及离子交换树脂，填充于上述支撑体的多个气孔。
