Abstract
본 발명은 산소 이온화 반응이 주로 일어나는 삼상 계면의 면적을 늘리기 위하여 전해질 분말의 도포 등의 방법으로 전해질 표면에 요철을 주고 공기극 전극을 입히는 방법으로 고체 전해질 연료 전지의 분극 현상을 개선하여 전지 성능을 향상시킬 수 있는 표면 요철을 갖는 고체 전해질 연료 전지를 제공하기 위한 것이다.The present invention improves the cell performance by improving the polarization phenomenon of the solid electrolyte fuel cell by applying unevenness to the surface of the electrolyte and coating the cathode electrode in order to increase the area of the three-phase interface in which the oxygen ionization reaction mainly occurs. It is to provide a solid electrolyte fuel cell having surface irregularities.
본 발명의 표면 요철을 갖는 고체 전해질 연료 전지는 전해질 표면에 1㎛ 이상의 직경을 갖는 전해질 분말을 20㎛ 이하의 두께로 스프레이법 또는 스크린 인쇄법에 의해 도포하고 여기에 공기극 물질을 입혀서 된 것임을 특징으로 한다.The solid electrolyte fuel cell having the surface irregularities of the present invention is characterized by applying an electrolyte powder having a diameter of 1 μm or more to the surface of the electrolyte by a spray method or a screen printing method with a thickness of 20 μm or less, and coating the cathode material thereon. do.
본 발명의 장점은 공기극의 분극 저항을 획기적으로 감소시켜 연료 전지의 성능을 종래 보다 15% 이상 증가 시킴에 따라 상용시 막대한 연료의 절감 효과를 나타낼 수 있다.An advantage of the present invention is to dramatically reduce the polarization resistance of the air electrode to increase the performance of the fuel cell by 15% or more than the conventional can exhibit a significant fuel savings in commercial use.
