Description

고체 산화물 연료전지의 챔버 구조Chamber Structure of Solid Oxide Fuel Cell
본 발명은 고체 산화물 연료전지의 챔버 구조에 관한 것으로, 더욱 상세하게는 연료전지의 출력 값을 향상시킬 수 있는 고체 산화물 연료전지의 챔버 구조에 관한 것이다.The present invention relates to a chamber structure of a solid oxide fuel cell, and more particularly to a chamber structure of a solid oxide fuel cell that can improve the output value of the fuel cell.
고체 산화물 연료전지(Solid Oxide Fuel Cell)는 산소 또는 수소 이온전도성을 띄는 고체 산화물을 전해질로 사용하여 연료 전지 중 가장 높은 온도(700∼1000 ℃)에서 작동한다.Solid Oxide Fuel Cells operate at the highest temperatures (700-1000 ° C) of fuel cells using solid oxides with oxygen or hydrogen ion conductivity as electrolytes.
특히, 고체 산화물 연료전지는 모든 구성 요소가 고체로 이루어져 있기 때문에 다른 연료 전지에 비해 구조가 간단하고, 전해질의 손실 및 보충과 부식의 문제가 없으며, 귀금속 촉매가 필요 없고 직접 내부 개질을 통한 연료 공급이 용이하다. 또한, 고온의 가스를 배출하기 때문에 폐열을 이용한 열 복합 발전이 가능하다는 장점도 지니고 있다. In particular, solid oxide fuel cells have a simpler structure than other fuel cells because all components are solid, there is no problem of electrolyte loss, replenishment and corrosion, no precious metal catalyst, and fuel supply through direct internal reforming. This is easy. In addition, it has the advantage that thermal combined cycle power generation using waste heat is possible because the high-temperature gas is discharged.
일반적인 고체 산화물 연료전지는 산소 이온전도성의 치밀한 전해질층과 그 양면에 위치한 다공성의 공기극(Cathode) 및 연료극(Anode)으로 이루어져 있다. 작동원리는 다공성의 공기극에서는 산소가 투과하여 전해질 면에 이르고 산소의 환원 반응에 의해 생성된 산소이온이 치밀한 전해질을 통해 연료극으로 이동하여 다시 다공성의 연료극에 공급된 수소와 반응함으로써 물을 생성하게 되고, 이때, 연료극에서는 전자가 생성되고 공기극에서는 전자가 소모되므로 두 전극을 서로 연결하면 전기가 흐르게 되는 것이다.A typical solid oxide fuel cell is composed of a dense electrolyte layer of oxygen ion conductivity and a porous cathode and anode located on both sides thereof. The operating principle is that oxygen permeates through the porous cathode and reaches the electrolyte surface. Oxygen ions generated by the oxygen reduction reaction move to the fuel electrode through the dense electrolyte and react with hydrogen supplied to the porous anode to generate water. At this time, since electrons are generated at the anode and electrons are consumed at the cathode, electricity flows when the two electrodes are connected to each other.

For example, the three-stage type chamber in which the cathode chamber 110 is in close contact with the upper and lower sides has been described as an example, but the present invention is not limited thereto.
애노드 챔버(Anode chamber: 100)는 수소 또는 메탄올, 에탄올 및 탄화수소계열 등이 포함되는 연료가 유입되도록 유입구가 형성되는 챔버로, 스테인리스(Stainless) 재질 등으로 형성된다.The anode chamber 100 is a chamber in which an inlet is formed so that fuel including hydrogen or methanol, ethanol, hydrocarbons, and the like is introduced therein, and is formed of a stainless material.
캐소드 챔버(Cathode chamber: 110)는 애노드 챔버(100)의 표면과 이면에 각각 적층되어 공기가 유입되는 유입구가 형성되며, 상기 애노드 챔버(100)와 동일 재질로 형성될 수 있다.The cathode chamber 110 is stacked on the front and rear surfaces of the anode chamber 100 to form an inlet through which air is introduced, and may be formed of the same material as the anode chamber 100.
절연체(120)는 애노드 챔버(100)와 연료전지 셀(130)과의 접촉 부위에 개입시켜 상기 애노드 챔버(100)의 재질인 스테인리스가 상기 연료전지 셀(130)과 집전하게 되는 문제를 해결할 수 있다.The insulator 120 may solve the problem that stainless steel, which is a material of the anode chamber 100, collects with the fuel cell 130 by intervening in contact between the anode chamber 100 and the fuel cell 130. have.
이때, 상기 절연체(120)는 절연체 물질로 사용되고 있는 세라믹 등으로 형성되며, 세라믹 중에서도 알루미나 플레이트(Al2O3) 등으로 가공하여 플레이트 형태로 만든 후 플레이트 표면에 연료전지 셀(130)이 삽입되는 홈을 형성한다.In this case, the insulator 120 is formed of a ceramic or the like that is used as an insulator material, and processed into an alumina plate (Al 2 O 3 ) among the ceramics to form a plate, and then the fuel cell 130 is inserted into the plate surface. Form a groove.

Since the fuel cell 130 seals the insulator 120 supported by the fuel cell 130, gas leakage does not occur while fuel is introduced into the cathode chamber 110.
더욱이, 상기 애노드 챔버(100)를 기준으로 양 표면에 캐소드 챔버(110)를 적층시키고, 그 내부의 연료전지 셀(130)을 직렬 연결하므로 각각의 상기 연료전지 셀(130) 들은 출력 값이 높아지게 된다.Furthermore, since the cathode chambers 110 are stacked on both surfaces of the anode chamber 100 and the fuel cell cells 130 are connected in series to each other, the fuel cell cells 130 have higher output values. do.
