Zusammenfassung:The present invention relates to a method for manufacturing a porous electrode in which a multi-type positive ion oxide catalyst is impregnated by using a CTAB stabilizer. More specifically, the method comprises: a step of preparing a button cell in which an electrolyte layer and a porous positive electrode layer are successively coated on a Ni-YSZ-based fuel electrode support; a step of preparing an amino acid-based nano catalyst solution for uniformly controlling compositions and nano structures of multi-type ions by using CTAB as a stabilizer; a step of infiltrating the prepared amino acid-based nano catalyst solution in the porous positive electrode layer of the button cell; and a step of drying and plasticizing the button cell. According to the present invention, a porous electrode having maximized electrode reaction at low operation temperature can be manufactured. 본 발명은 CTAB 안정화제를 이용한 다종양이온 산화물촉매가 함침된 다공성 전극의 제조방법에 관한 것으로, 보다 구체적으로는 Ni-YSZ로 이루어진 연료전극 지지체 상에 전해질층 및 다공성 양극층이 순차적으로 코팅된 버튼 셀을 준비하는 단계; CTAB를 안정화제로 이용하여 다종양이온의 조성 및 나노구조를 균질하게 제어하기 위한 아미노산계 나노촉매 용액을 준비하는 단계; 준비된 상기 아미노산계 나노촉매 용액을 상기 버튼 셀의 다공성 양극층에 침윤시키는 단계; 및 상기 버튼 셀을 건조 및 소성시키는 단계를 포함하는 것을 특징으로 한다.
