Abstract
본 발명은 천연가스를 개질한 가스를 연료로 하고 공기를 산화제로 하는 용융탄산염형 연료전지에 관한 것으로, 특히 채널판은 양면에칭에 의해 가스유로를 형성하고, 마스크판들은 와이어-커팅하여 분배기 및 전극수납 홈을 형성하여 레이저 용접에 의해 일체화한 에칭가공된 연료전지분리판에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molten carbonate fuel cell having a gas reformed from natural gas as a fuel and an air as an oxidant. In particular, the channel plate forms a gas flow path by double-side etching, and the mask plates are wire-cut to divider and The present invention relates to an etched fuel cell separator formed by electrode welding grooves and integrated by laser welding.
본 분리판은 채널판을 에칭에 의해 양면을 가공하므로 제작시 변형을 최소화할 수 있는 잇점을 갖는다. 변형을 최소화하므로 전극에 균일한 하중이 작용하게 되어 전극의 균열방지에도 탁월한 효과를 갖는다. 뿐만아니라, 부품수가 감소함으로써 제작비를 감축할 수 있으며, 종국적으로는 상기한 효과들로 인해 연료전지의 성능을 향상시킬 수 있는 특징을 갖는다.This separation plate has an advantage of minimizing deformation during fabrication because it processes both sides by etching the channel plate. Since the deformation is minimized, a uniform load is applied to the electrode, which has an excellent effect on preventing cracking of the electrode. In addition, the manufacturing cost can be reduced by reducing the number of parts, and ultimately, the above-described effects can improve the performance of the fuel cell.
