    • A method for the production of a gas diffusion electrode is described, and especially a method for producing a plastic bounded thin gas diffusion electrode with high catalytic activity for the oxygen or the hydrogen reaction. The method comprising the following steps: agglomerating a powder mixture with PTFE particles in a dry form to produce a dry agglomerate; adding an organic solvent to the dry agglomerate to produce a paste; calendering the paste into a thin sheet with a thickness less than 1mm, to form an active layer or gas diffusion layer; in which one or both contain a current collector; and combining said active layer and said gas diffusion layer to form the gas diffusion electrode. The gas diffusion electrode thus produced may be used for example in fuel cells, metal-air batteries or membranes.
    • 对气体扩散电极的制造方法进行了说明,特别是对氧气或氢气反应具有高催化活性的塑料有界薄的气体扩散电极的制造方法。 该方法包括以下步骤:将粉末混合物与干燥形式的PTFE颗粒结块以产生干燥的团聚体; 向干燥的附聚物中加入有机溶剂以产生糊状物; 将糊料压延成厚度小于1mm的薄片,以形成活性层或气体扩散层; 其中一个或两个包含集电器; 并且组合所述有源层和所述气体扩散层以形成气体扩散电极。 这样制造的气体扩散电极可以用于例如燃料电池,金属空气电池或膜。
