利用電紡技術製備聚二氟乙烯-六氟丙烯共高分子纖維 (PVdF-co-HFP) 奈米纖維,以此奈米纖維膜為支撐物浸漬Nafion溶液製作Nafion/PVdF-co-HFP 纖維質子交換複合膜。將此複合膜製作膜電極組(MEA)進行H2/O2 燃料電池測試。實驗數據顯示在80。C無背壓,陽極與陰極觸媒Pt塗佈量分別為 0.2 mg/cm2及 0.4 mg/cm2 條件下,最高功率密度可達約 992 mW/cm2。數據顯示複合膜應用於 PEMFC 具有極大發展潛力。
Electrospinning technology to prepare the poly(vinylidene fluoride-co-hexafluoro-propylene ) (PVdF-co-HFP) nanofibers, this nanofibers membrane as the support material impregnated with Nafion solution produced Nafion / PVdF-co-HFP fiber proton exchangecomposite film. This composite membrane production of membrane electrode assembly (MEA) H2/O2 fuel cell testing. The experimental data show that at 80。 C with no back pressure, the anode and cathode catalyst of Pt coating weight of 0.2 mg/cm2 and 0.4 mg/cm2. The maximum power density of up to about 992 mW/cm2. The data show that the composite membranes used in PEMFC has great development potential.
