ePTFE-supported polyelectrolyte membranes made with ionomer-Kynar blends

Abstract

本发明涉及用离聚物-Kynar共混物制备的ePTFE支持的聚电解质膜。用于燃料电池的复合膜,包括具有预定的空隙体积的膨胀聚四氟乙烯基质,各自填充至少部分所述空隙体积的第一聚合物和第二聚合物。所述第一聚合物包括以下化学部分:。还提供了结合有所述复合膜的聚合物电解质膜以及燃料电池。
The invention relates to ePTFE-supported polyelectrolyte membranes made with ionomer-Kynar blends. A composite membrane for fuel cells includes an expanded polytetrafluoroethylene substrate having a predefined void volume, a first polymer and a second polymer each of which fill at least a portion of the void volume. The first polymer includes the following chemical moiety: Polymer electrolyte membranes and fuel cells incorporating the composite membrane are also provided.
