A bipolar separator for fuel cells according to the present invention has a larger area than an existing one to reduce the number of stacks so that lightweight and compactness are possible, has a curved surface that matches the surface on which a fuel cell is installed so that design freedom is increased and mobility itself can be made lighter, and has multiple inlets and multiple outlets, thereby improving the reaction efficiency of hydrogen and oxygen and resolving flow stagnation. 본 발명에 따른 연료전지용 양극성 분리판은 기존에 비해 대면적이므로 적층 횟수가 줄어들고 이에 따라 경량화, 컴팩트화가 가능하며, 연료전지가 설치되는 면과 형합하는 곡면을 가지므로 설계 자유도가 증가하고 모빌리티 자체의 경량화가 가능하고, 여러 개의 유입구와 여러 개의 유출구(Multi Input Multi Output)를 가지므로 수소와 산소의 반응효율을 향상시킬 수 있고 유동 정체 부분의 해소가 가능하다는 장점을 갖는다.
