Fuel cell electrode |
摘要 |
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.
