NEPEM氢燃料电池用质子交换膜
NEPEM Proton exchange membrane for hydrogen fuel cell
在传统质子交换膜基础上加入了e PTFE(膨体聚四氟乙烯)微孔增强材料，具 有强度高、电导率高、离子渗透率低等特点。With ePTFE (expanded polytetrafluoroethylene)microporous reinforcing material joined in the traditional proton exchange membrane,Thinkre PEM is characterized by high strength,high conductivity and low ion permeability.
