Development of the Low Cost Assembled Separator
저가형 조립 분리판의 개발
Abstract
This study considers the feasibility of using the low cost assembled separator. The graphite plate has been widely used as the separator in the field of PEMFCs(Polymer electrolyte membrane fuel cell) industry because of its excellent material properties such as good corrosion resistance, good electrical conductance and so on. However, there are some problems for the commercialization due to its poor cost effectiveness for the large volume manufacturing and lack of mechanical strength. From this respect, this study has focused on the manufacturing technology in order to reduce the price for the commercialization of separator. This study also shows that the assembled separator of the suggested structure, which is composed of grafoil and PC(PolyCarbonate) materials, could be manufactured at low cost enough for the mass production. The flow fields produced by cutting foils and the base plates of the separators were simply made by mechanical work.
