Abstract:
PURPOSE: A composition for a separator for a fuel cell, a manufacturing method thereof, the separator for the fuel cell including thereof, and the fuel cell are provided to reduce the cost, facilitate the manufacturing process, and reduce the weight of the separator. CONSTITUTION: A composition for a separator for a fuel cell contains a polymer including 10~70wt% of first conductive additive, and 0.1~10wt% of second conductive additive. A manufacturing method of the composition comprises the following steps: mixing the conductive additives; stirring the mixture; and compression-molding the mixture.
Abstract:
연료전지 분리판용 조성물, 그 제조방법, 이를 포함하는 연료전지 분리판 및 연료전지가 제공된다. 본 발명에 따른 연료전지 분리판용 조성물은 제 1 전도성 첨가제; 및 상기 제 1 첨가제보다 작은 크기의 제 2 전도성 첨가제를 포함하며, 제 1 전도성 첨가제는 전체 조성물의 10 내지 70중량%이고, 제 2 전도성 첨가제는 0.1 내지 10중량%인 것을 특징으로 하며, 기존의 흑연 분리판보다 가격이 저렴하고, 제작이 용이할 뿐만 아니라, 가벼운 무게를 갖는 장점이 있으며, 다른 제조 방법에 의하여 제조된 분리판에 비하여 전기전도도를 향상시키는 효과를 갖는다.
Abstract:
PURPOSE: A polypropylene composite is provided to obtain biodegradability, to maintain flexibility, chemical resistance, and heat resistance of the polypropylene which is capable of being used as an interior material of an automobile and to improve mechanical properties. CONSTITUTION: A polypropylene composite includes a polymer blend comprising polypropylene and a biodegradable polymer and maleic anhydride graft polypropylene. The biodegradable polymer is selected from polylactic acid, polycaprolactone], or polyhydroxybutylate. The maleic anhydride graft polypropylene includes 0.1-5.0 weight% of maleic anhydrides. The weight ratio of the polypropylene and the biodegradable polymer is 9:1-7:3.
