Abstract
본 발명은 바이폴라 멤브레인에 대한 것이며, 양이온시트 및 음이온 시트 사이에 촉매를 형성하며, 음이온 시트 표면에 형성된 돌기에 의해 양이온시트와의 결합성을 향상시키는 것을 목적으로 한다. 구체적으로 제1이오노머로 제1시트(110)를 형성하는 제1시트층형성단계(S100); 상기 제1시트층 형성단계 후, 제1시트층의 일면에 촉매층(130)을 형성하는 촉매층형성단계(S300); 상기 촉매층형성단계 후, 촉매층 일면에 제2이오노머로 제2시트층(120)을 형성하는 제2시트층형성단계(S500);를 시계열적 단계로 형성된다. The present invention relates to a bipolar membrane, and its purpose is to form a catalyst between a cation sheet and an anion sheet and improve bonding with the cation sheet by protrusions formed on the surface of the anion sheet. Specifically, a first sheet layer forming step (S100) of forming a first sheet 110 with a first ionomer; After the first sheet layer forming step, a catalyst layer forming step (S300) of forming a catalyst layer 130 on one surface of the first sheet layer; After the catalyst layer forming step, a second sheet layer forming step (S500) of forming a second sheet layer 120 with a second ionomer on one side of the catalyst layer is formed in time series.
