Abstract
저온 저압에서 작동되는 실험용 단위 연료전지를 제작하여 전극의 구조변화에 따른 전지의 성능을 비교 검토하였다. 전지의 연료로는 수소, 산화제로는 산소 그리고 전해액으로는 KOH를 사용하였다. 수소전극과 산소전극은 동일한 방법으로 제조하였는 바 carbonyl nickel과 ammonium bicarbonate의 함량을 변화시켜서 기공구조가 달라지게 하였다. 실험결과 전기화학적 반응속도는 저기화학반응이 일어나는 비표면적 뿐만 아니라 대기공과 소기고의 적절한 조합에도 크게 의존함을 알 수 있었다.
An experimental low-temperature hydrogen-oxygen fuel cell was constructed and its performance was tested for various electrode structures. Both electrodes for hydrogen and oxygen were made by the same method and various double porous structures of the electrode were obtained by changing the contents of carbonyl nickel and am-monium bicarbonate. Experimental results show that electrochemical reaction velocity depends not only on the specific surface area where electrochemical reaction occurs but also on the ratio of large pores and small pores of the electrode.
