본 발명은 고체산화물 전기분해셀과 고체산화물 연료전지를 이용한 하이브리드 발전시스템에 관한 것으로, 보다 상세하게는 별도의 수소 등의 공급없이 수증기만 공급하여도, SOEC에서 수소를 생산하고 , 별도의 저장장치 없이 SOFC에 수소를 공급함으로서 수소의 연료비를 절감할 수 있다는 장점이 있는 고체산화물 전기분해셀과 고체산화물 연료전지를 이용한 하이브리드 발전시스템에 관한 것이다. The present invention relates to a hybrid power generation system using a solid oxide electrolysis cell and a solid oxide fuel cell. More specifically, even if only water vapor is supplied without supplying hydrogen, a separate storage device is produced in SOEC. The present invention relates to a hybrid power generation system using a solid oxide electrolysis cell and a solid oxide fuel cell, which have an advantage of reducing hydrogen fuel cost by supplying hydrogen to SOFC.

1870년대 Jules Vemes가 물이 미래에 연료로써 사용될 것이라 주창한 이래 물은 수소와 산소로 반복하여 이용 가능한 재생가능성을 갖는 이상적인 수소 연료로 생각되고 있다. 현재 지구 온난화와 화석연료의 고갈에 따른 대체에너지의 연구개발에 대한 요구가 지속적으로 높아지고 있는 가운데 실용 가능성 있는 환경 및 에너지 문제해결의 유일한 대안으로 수소에너지가 주목받고 있는데, 전기에너지를 이용하여 순수한 물로부터 수소를 생산하는 기술 중의 하나인 고체산화물을 이용한 고온수증기 전해기술의 경우 전해질과 분리막으로 구성되며 수소 또는 산소이온 전도성을 갖는 산화물 막을 이용하는 기술로 700-900oC의 고온운전조건을 특징으로 하며 고체산화물 전기분해셀 (Solid Oxide Electrolyzer Cell, SOEC)이다. 이는 표1에 의해서 정리된 전기화학반응을 통해서 설명이 가능하다. 이에 대해서 상술하자면 고체산화물 전기분해셀에 주입된 수증기는 외부 전원을 고체산화물에 인가했을 경우 연료극에서 순수한 수소가 발생되며 캐쏘드에서 순수한 산소와 함께 2개의 전자가 발생하게 된다.Since Jules Vemes advocated water in the future in the 1870s, water has been considered the ideal hydrogen fuel with renewables that can be used repeatedly with hydrogen and oxygen. Currently, demand for research and development of alternative energy due to global warming and depletion of fossil fuels is continuously increasing, and hydrogen energy is attracting attention as the only alternative to solving the viable environment and energy problems. The high temperature steam electrolytic technology using solid oxide, which is one of the technologies for producing hydrogen from, consists of electrolyte and separator and uses oxide film with hydrogen or oxygen ion conductivity and features high temperature operating condition of 700-900 o C. Solid Oxide Electrolyzer Cell (SOEC). This can be explained through the electrochemical reactions summarized in Table 1. In detail, the water vapor injected into the solid oxide electrolysis cell generates pure hydrogen from the anode when external power is applied to the solid oxide, and generates two electrons together with pure oxygen from the cathode.

반면, 대기 중에 풍부한 수소와 산소를 이용, 전력을 생산하는 시스템 중 하나는 고체산화물 연료전지(Solid Oxide Fuel Cell, SOFC)이다. 고체산화물 연료전지는 공기와 산소의 반응에 따른 화학에너지를 전기에너지로 변환시킨다. 이는 표2에 의해서 정리된 전기화학반응을 통해서 설명이 가능하다. 이에 대해서 상술하자면 고체산화물 연료전지에서는 캐쏘드에 공기가 주입될 경우 산소분자는 산소이온으로 환원이 되며 산소이온은 전해질을 통과하여 애노드에 공급된 수소와 산화작용을 하여 물과 함께 외부 전원을 제공할 수 있는 두 개의 전자를 발생시킨다. On the other hand, one of the systems that generate power by using abundant hydrogen and oxygen in the atmosphere is a solid oxide fuel cell (SOFC). A solid oxide fuel cell converts chemical energy into electrical energy according to a reaction between air and oxygen. This can be explained through the electrochemical reactions summarized in Table 2. In detail, in the solid oxide fuel cell, when air is injected into the cathode, oxygen molecules are reduced to oxygen ions, and oxygen ions pass through an electrolyte to oxidize with hydrogen supplied to the anode to provide an external power source with water. It generates two electrons that can.
