    • A sheet material, principally comprised of a polymer such as polytetrafluoroethylene, having characteristics which permit its use in a fuel cell electrode is formed from co-agglomerates of the polymer and a pore former. In a fuel cell electrode application, the polymer-pore former agglomerates are themselves caused to co-agglomerate with a catalyst, the resulting co-agglomerates are formed into a layer and the pore former is leached from the layer so as to produce a structure having gas channels only in the polymer portions thereof. Agglomeration of the pore former and polymer particles is permitted through first imparting a positive charge to the pore former particles. The gas permeable catalyst layer will be bonded to a support plate to define a fuel cell electrode.
    • 主要由诸如聚四氟乙烯的聚合物组成的片材,其具有允许其在燃料电池电极中使用的特性由聚合物和成孔剂的共附聚物形成。 在燃料电池电极应用中,本身引起聚合物 - 成孔剂附聚物与催化剂共附聚,所得的共附聚物形成一层,并且从层中沥滤成孔剂以产生具有 气体通道仅在其聚合物部分中。 通过首先向成孔剂颗粒赋予正电荷,允许成孔剂和聚合物颗粒的聚集。 气体可渗透催化剂层将结合到支撑板以限定燃料电池电极。
