Description

수소 연료전지용 막전극 접합체 제조장치A membrane electrode assembly manufacturing apparatus for a hydrogen fuel cell
본 발명은 수소 연료전지의 막전극 접합체를 롤투롤 방식으로 연속하여 제조하는 장치에 관한 것이다. The present invention relates to an apparatus for continuously producing a membrane electrode assembly of a hydrogen fuel cell by a roll-to-roll method.
일반적으로 수로 연료전지(이하 연료전지 이라함.)는 수소와 산소가 가지고 있는 화학에너지를 전기화학반응에 의하여 전기에너지로 변환시키는 발전 시스템이다. Generally, a waterway fuel cell (hereinafter referred to as a fuel cell) is a power generation system that converts chemical energy possessed by hydrogen and oxygen into electrical energy by an electrochemical reaction.
즉, 연료의 산화로 인해 생기는 화학 에너지를 직접 전기 에너지로 변환시키는 것으로, 공기극(Cathode)에서는 산소의 환원반응이, 연료극(Anode)에서는 수소의 산화반응이 전기화학적으로 진행된다. That is, the chemical energy generated due to the oxidation of the fuel is directly converted into electric energy, and the reduction reaction of oxygen is performed in the cathode and the oxidation reaction of hydrogen in the anode proceeds electrochemically.
전체적인 연료전지의 반응은 물의 전기분해 역반응으로서, 이 과정에서 전기를 비롯하여, 열, 물이라는 세가지 생산물이 생성된다.The reaction of the whole fuel cell is the reverse reaction of the electrolysis of water. In this process, three products such as electricity, heat and water are produced.
그리고 이러한 연료전지는, 고분자 전해질막과 전극(연료극, 공기극), 가스확산층(GDL: Gas Diffusion Layer),분리판(Separator)을 포함하는 구성으로 이루어진다. The fuel cell includes a polymer electrolyte membrane, an electrode (anode, cathode), a gas diffusion layer (GDL), and a separator.
한편, 전기에너지로의 변환은 막전극 접합체에서 이루어지므로 막전극 접합체는 연료전지의 성능을 좌우하는 핵심부품이다. On the other hand, since the conversion into electric energy is performed in a membrane electrode assembly, the membrane electrode assembly is a key component that determines the performance of the fuel cell.
고분자 전해질 연료전지의 스택 내부 구조는 전해질막 및 상기 전해질막의 양면 각각에 형성되는 전극재인 한쌍의 전극 촉매층으로 구성된 막전극 접합체를 포함한다. The stack internal structure of the polymer electrolyte fuel cell includes an electrolyte membrane and a membrane electrode assembly composed of a pair of electrode catalyst layers, which are electrode materials formed on both sides of the electrolyte membrane.
이러한 막전극 접합체의 양면 각각에는, 한쌍의 가스확산층(gas diffusion layer: GDL)이 막전극 접합체를 지지하도록 배치되며, 가스확산층의 바깥쪽 부분에는 연료 및 공기를 전달하고 생성된 물을 배출하는 유로(flow field)가 형성된 한쌍의 분리판(seperator)이 배치된다. A gas diffusion layer (GDL) is disposed on each of both surfaces of the membrane electrode assembly so as to support the membrane electrode assembly. The gas diffusion layer is connected to the outside of the gas diffusion layer, a pair of separators formed with flow fields are disposed.
따라서, 단위 연료전지는 1장의 막전극 접합체와 2장의 가스확산층 및 2장의 분리판(sepeator)으로 구성되며, 이러한 단위전지가 적층됨으로써 스택전지를 제조완성하게 된다. Therefore, the unit fuel cell is composed of one membrane electrode assembly, two gas diffusion layers and two separators, and the stacked cells are fabricated by stacking the unit cells.
