The present invention relates to a direct combustion type solid oxide fuel cell stable under fast driving conditions. The direct combustion type solid oxide fuel cell of the present invention uses YSZ having excellent mechanical strength as an electrolyte, has an effect of increasing resistance to thermal shock by adjusting the thickness of the electrolyte to be thin through a tape-casting process, has an effect of increasing performance of a cell, and can be useful as a portable fuel cell due to excellent portability. 본 발명은 급속 구동 조건에서 안정한 직접 연소형 고체산화물 연료전지에 관한 것으로, 본 발명의 직접 연소형 고체산화물 연료전지는 기계적 강도가 우수한 YSZ를 전해질로 사용하며, 테이프 캐스팅(tape-casting)공정을 통해 전해질의 두께를 얇게 조절함에 따라, 열충격에 대한 저항성이 증가된 효과를 가지며, 셀의 성능이 향상되는 효과를 가지며, 휴대성이 우수하여 휴대용 연료전지로 유용할 수 있다.
