Description

5-레이어 멤브레인 제작을 위한 열 가압형 지그{Heat pressure-type jig for manufacturing 5-layer membrane}Heat pressure-type jig for manufacturing 5-layer membrane

본 발명은 5-레이어 멤브레인 제작을 위한 열 가압형 지그에 관한 것으로서, 별도의 외부가이드를 설치하여 이온교환막어셈블리(MEA)가 히팅 플레이트와 분리되고, 금속판이 히팅 플레이트에 일체로 결합되어 금속판의 온도가 일정기간 유지되며, 스프링 구조를 도입하여 가스확산층의 두께에 따른 외부가이드의 위치 조절이 능동적으로 이루어지는 5-레이어 멤브레인 제작을 위한 열 가압형 지그에 관한 것이다.The present invention relates to a heat pressurizing jig for manufacturing a five-layer membrane, wherein an ion exchange membrane assembly (MEA) is separated from the heating plate by installing a separate external guide, and the metal plate is integrally coupled to the heating plate to heat the metal plate. Is maintained for a certain period of time, and a spring structure is introduced to the thermal pressurized jig for manufacturing a five-layer membrane active position control of the outer guide according to the thickness of the gas diffusion layer.

일반적으로 연료전지에서 공급가스(수소, 공기)를 반응시키는 전극촉매와 수소이온을 전달시켜주는 전해질막을 이온교환막어셈블리(Membrane Electrode Assembly;MEA, 이하 "MEA"라 칭한다.)라 한다. In general, an electrode catalyst for reacting a supply gas (hydrogen, air) and an electrolyte membrane for delivering hydrogen ions in a fuel cell are referred to as a membrane exchange assembly (MEA, hereinafter referred to as "MEA").

또한, 분리판 유로에서 공급된 가스를 균일하게 분산시켜주고 반응가스의 전기화학반응으로 생성된 물을 효과적으로 배출시켜주는 역할을 하는 가스확산층(Gas Diffusion Layer:GDL, 이하 "GDL"이라 칭한다. )이 존재한다. In addition, the gas diffusion layer (GDL, hereinafter referred to as "GDL") serves to uniformly disperse the gas supplied from the separator flow channel and effectively discharge the water generated by the electrochemical reaction of the reaction gas. This exists.

이러한 MEA와 GDL, 분리판이 차례로 적층되어서 연료전지 스택을 구성하게된다. 이때, MEA와 GDL을 결합시켜 모듈화 하면 스택의 생산성이 증가하게 된다. The MEA, the GDL, and the separator are sequentially stacked to form a fuel cell stack. At this time, if the modularization by combining the MEA and GDL increases the productivity of the stack.

이하 첨부도면을 참조하여 5-레이어 멤브레인 및 이를 제작하는 방법에 대해 설명하기로 한다.Hereinafter, a 5-layer membrane and a method of manufacturing the same will be described with reference to the accompanying drawings.

첨부한 도 1은 5-레이어 멤브레인의 개시도이고, 도 2a 및 도 2b는 5-레이어 멤브레인의 제작시 주의점을 나타낸 도면이다.1 is a view illustrating a five-layer membrane, and FIGS. 2A and 2B are diagrams showing precautions when manufacturing a five-layer membrane.

흔히, MEA(130)는 수소 전극촉매(110), 고체전해질막(100), 공기 전극촉매(120)로 이루어져서 "3-레이어"로 명명하며, 도 1에서 도시한 바와 같이, 양쪽 전극에 GDL(140)이 각각 1장씩 붙게 되는데, 제조시 작업편의성을 위해서 MEA(130)와 GDL(140) 2장을 결합하여 하나의 제품으로 제조하고 이를 "5-레이어 MEA(90)"라 칭한다.Commonly, the MEA 130 is composed of a hydrogen electrode catalyst 110, a solid electrolyte membrane 100, and an air electrode catalyst 120, and is referred to as a "3-layer". As shown in FIG. Each one of the 140 is attached, for the convenience of manufacturing in manufacturing two MEA (130) and GDL (140) to combine into a single product, which is referred to as "5-layer MEA (90)".

상기 5-레이어 MEA(90)를 만들기 위해서는 구성품을 순서대로 적층한후 위치를 맞추어 일정시간동안 일정한 온도와 압력으로 힘을 가하여 접합시킨다.In order to make the 5-layer MEA (90), the components are stacked in order and then bonded to each other by applying a force at a constant temperature and pressure for a predetermined time.

상기 온도와 압력은 제품의 특성에 따라 변하게 되며, 필요에 의해서 접합을 위한 각종 첨가제를 넣기도 한다. The temperature and pressure will vary depending on the characteristics of the product, and if necessary add various additives for bonding.

또한, 5-레이어 MEA(90)의 제조를 위해서는 온도와 압력을 조절할수 있는 핫프레스(Hot Press)와 정확한 위치에 구성품을 위치시킬수 있는 결합용 지그가 필요하다.In addition, for the manufacture of the five-layer MEA (90) requires a hot press (Hot Press) to control the temperature and pressure and a jig for coupling to position the components in the correct position.

상기 5-레이어 MEA(90)의 구성품을 적층하기 위해서는 GDL(140)-MEA(130)- GDL(140)의 순으로 구성품을 차례로 놓고 가열된 핫플레이트(Hot Plate)로 양쪽 GDL부분에 압력을 균일하게 가해야 한다.To stack the components of the 5-layer MEA 90, the components are sequentially placed in the order of GDL 140, MEA 130, and GDL 140, and pressure is applied to both GDL portions with a heated hot plate. It should be applied evenly.

여기서, 주의해야 할 점은 도 2a에서 도시한 바와 같이, 양쪽 GDL(140)이 결합시 MEA(130)의 촉매부(110, 120)를 완전히 덮고, 양쪽 GDL(140) 위치가 정확히 일치하여하 한다는 점이다. Here, it should be noted that, as shown in Figure 2a, both GDL (140) completely covers the catalyst unit (110, 120) of the MEA (130) when combined, and both GDL (140) positions exactly match Is that.

만약, 도 2b에서 도시한 바와 같이, GDL(140)이 전극촉매(110, 120)를 다 덮지 못할경우 촉매에 충분이 가스를 전달하지 못하여 연료전지의 성능이 감소하고, GDL(140)이 분리판 외각으로 나오게 되면 연료전지제조 자체가 불가능하게 된다. If the GDL 140 does not cover the electrode catalysts 110 and 120 as shown in FIG. 2B, the performance of the fuel cell is reduced due to insufficient gas transfer to the catalyst, and the GDL 140 is separated. When it comes to the outer shell, fuel cell manufacturing itself is impossible.

또한, 양쪽 GDL(140)의 위치가 일치하지 못하면 연료전지 제조시 힘의 불균형이 발생하여 연료전지의 성능이 저하하게 된다.In addition, when the positions of the two GDLs 140 do not match, a force imbalance occurs in manufacturing the fuel cell, thereby degrading the performance of the fuel cell.

이러한 열 가압형 지그와 관련하여, 일본특개 제2000-208140호에는 평행하게 배치된 가열형 가압본체의 사이에 전극부재의 적층제를 삽입하고 가열, 가압하는 지그가 개시되어 있다.In connection with such a thermo-pressing jig, Japanese Laid-Open Patent Publication No. 2000-208140 discloses a jig for inserting, heating and pressurizing a laminating agent of an electrode member between heated pressurized bodies arranged in parallel.

또한, 미국특허 제6,613,470호에는 전체적인 가열, 가압에 의해 MEA를 제조하기 전에, 부분적으로 미리 가열, 가압하여 가고정상태를 유지시키는 지그가 개시되어 있다.Further, U. S. Patent No. 6,613, 470 discloses a jig for partially preheating and pressing to maintain a temporarily fixed state before manufacturing the MEA by total heating and pressurization.

이하 첨부 도면을 참조하여 종래 5-레이어 MEA 제작을 위한 열 가압형 지그를 설명하기로 한다.Hereinafter, a thermal pressurizing jig for manufacturing a conventional 5-layer MEA will be described with reference to the accompanying drawings.

첨부한 도 3은 종래 5-레이어 MEA 제작을 위한 열 가압형 지그의 개시도이다.FIG. 3 is a view showing a heat press type jig for manufacturing a conventional 5-layer MEA.

도 3에서 도시한 바와 같이, 메인바디(150) 중앙 공간에 금속하판(160)이 결합하고, 금속하판(160)의 상부에 하층GDL(170)이 삽입되며, 하층GDL 상부에 MEA(130)가 적층된다.As shown in FIG. 3, the lower metal plate 160 is coupled to the central space of the main body 150, the lower layer GDL 170 is inserted into the upper metal lower plate 160, and the MEA 130 is disposed above the lower layer GDL. Are stacked.

또한, 상기 적층된 MEA(130) 상부에 GDL가이드(190)가 장착되고, 그 위에 상층GDL(200)이 삽입되면 금속상판(210)을 덮은후, 핫프레스(미도시)로 온도와 압력을 가하여 5-레이어 MEA를 제작한다.In addition, the GDL guide 190 is mounted on the stacked MEA 130, and when the upper layer GDL 200 is inserted thereon, the metal top plate 210 is covered, and then a temperature and pressure are applied by a hot press (not shown). To prepare a 5-layer MEA.

여기서, 핫프레스의 핫플레이트부(미도시)와 금속상하판(160, 210)은 멀리 떨어져 있어서 온도유지가 어려우며, 금속상하판이 원하는 온도에 이르는데 과다한 시간이 소요되는 문제점이 있었다.Here, the hot plate portion (not shown) of the hot press and the metal upper and lower plates 160 and 210 are far from each other, so that it is difficult to maintain the temperature, and the metal upper and lower plates have an excessive time for reaching the desired temperature.

또한, 뜨거워진 금속하판(160) 위에 고분자 MEA(130)를 접한 상태로 올려놓게 되어 MEA가 수분증발에 의해 주름진 모양이 형성됨으로써, 접합성, MEA의 물성치 및 치수 안정성이 저하되는 문제점이 있다.In addition, since the polymer MEA 130 is placed in contact with the heated metal lower plate 160 in contact with the polymer MEA 130, a wrinkled shape of the MEA is formed by moisture evaporation.

덧붙여, 지그의 가압시 GDL(170, 200)이 압축되면서 GDL 외곽부와 맞닿는 MEA부위가 아래로 꺾여 들어가 물리적 파손의 위험이 발생하는 문제점이 있다.In addition, when the jig is pressed, the GDL (170, 200) is compressed while the MEA portion in contact with the outer GDL is bent down there is a problem that the risk of physical damage occurs.

따라서, 본 발명은 상술한 문제점을 해결하기 위해 발명된 것으로서, 기존의 지그 구조를 개선하여 5-레이어 멤브레인의 제작이 효율적으로 이루어지고, 특히 금속판이 히팅 플레이트에 일체로 형성되어 다수의 5-레이어 멤브레인 제작시 매번 금속판의 온도를 정상상태까지 재가열하는 번거로움이 줄어들며, MEA가 하부가이드와 일정 간격을 유지한채로 외부가이드에 장착되어 금속판에 의해 건조, 수축 및 변형되는 것이 방지되는 5-레이어 멤브레인 제작을 위한 열 가압형 지그를 제공하는데 그 목적이 있다.Therefore, the present invention has been invented to solve the above-described problems, the production of a five-layer membrane by efficiently improving the existing jig structure, in particular a metal plate is integrally formed on the heating plate a plurality of five-layer When manufacturing the membrane, the hassle of reheating the temperature of the metal plate to the normal state every time is reduced, and 5-layer membrane fabrication is prevented from being dried, shrunk and deformed by the metal plate by mounting the MEA on the outer guide while keeping a certain distance from the lower guide. The purpose is to provide a thermally pressurized jig for the purpose.

이하 첨부 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부한 도 4는 본 발명에 따른 5-레이어 멤브레인 제작을 위한 열 가압형 지그의 개시도이다.4 is a view illustrating a heat pressurizing jig for manufacturing a 5-layer membrane according to the present invention.

도 4에서 도시한 바와 같이, 하부 가스확산층(170)(Gas Diffusion Layer:GDL, 이하 "GDL"이라 칭한다.)이 적층된 금속하판(210)의 양쪽에 가이드스프링(220)으로 지지되는 하부가이드(230)가 설치되고, 하부가이드(230)의 상부에는 이온교환막어셈블리(Membrane Electrode Assembly;MEA, 이하 "MEA"라 칭한다.) 및 상부GDL(200)을 고정하는 외부가이드(270)가 설치되며, 외부가이드(270)의 상부에는 프레스(360)의 하강에 의해 외부가이드(270) 및 상부GDL(200)을 각각 가압하는 상판지지대(310) 및 금속상판(300)이 설치된다.As shown in FIG. 4, a lower guide supported by guide springs 220 on both sides of a metal lower plate 210 on which a lower gas diffusion layer 170 (GDL, hereinafter referred to as “GDL”) is laminated. 230 is installed, and an upper portion of the lower guide 230 is an ion exchange membrane assembly (MEA, hereinafter referred to as "MEA") and an outer guide 270 for fixing the upper GDL 200 is installed. On top of the outer guide 270, the upper plate support 310 and the metal upper plate 300 for pressing the outer guide 270 and the upper GDL 200 by the lowering of the press 360 are installed.

상기 금속하판(210)은 하부 히팅 플레이트(250)의 상부에 일체로 형성되어 하부 히팅 플레이트(250)에서 발생하는 열을 금속하판(210)의 상부에 적층된 하부GDL(170)에 전달한다.The lower metal plate 210 is integrally formed on the lower heating plate 250 to transfer heat generated from the lower heating plate 250 to the lower GDL 170 stacked on the upper metal lower plate 210.

상기 하부가이드(230)는 금속하판(210)의 양측에 밀접한 상태로 장착되어, 하부GDL(170)이 금속하판(210)의 상면에 적층시 하부GDL(170)이 정확한 지점에 위치하도록 안내하는 역할을 제공한다.The lower guide 230 is mounted in close contact with both sides of the metal lower plate 210 to guide the lower GDL 170 at the correct point when the lower GDL 170 is stacked on the upper surface of the metal lower plate 210. Provide a role.

이때, 양쪽 하부가이드(230) 사이의 거리는 하부GDL(170)의 길이만큼 유지되고, 하부가이드(230)이 높이는 금속하판(210)보다 돌출되어 하부GDL(170)이 양쪽 하부가이드(230) 사이에 안착되도록 한다.At this time, the distance between both lower guide 230 is maintained by the length of the lower GDL (170), the lower guide 230 is protruding than the lower metal plate 210 is raised so that the lower GDL (170) between both lower guide 230 Allow them to settle on.
