摘要： Diffusion media for fuel cell is made by preparing an aqueous dispersion comprising a powder resin, a binder material, and a fiber material comprising carbon fibers, of these; forming a layer of the dispersion on a support; removing water from the layer to form a fiber layer; molding the fiber layer; and carbonizing or graphitizing the molded layer.

摘要： A gas diffusion media for a fuel cell, such as a proton exchange membrane fuel cell, is provided. The gas diffusion media includes carbonizable acrylic pulp fibers instead of conventional phenolic resin as a binder material. The acrylic fibers are mixed with the carbon fiber dispersion during the papermaking step, thus eliminating the phenolic resin impregnation step typically associated with conventional gas diffusion media manufacturing processes. The mat is then cured and carbonized to produce gas diffusion media.
摘要翻译： 提供了用于燃料电池的气体扩散介质，例如质子交换膜燃料电池。 气体扩散介质包括可碳化的丙烯酸纸浆纤维，而不是传统的酚醛树脂作为粘合剂材料。 丙烯酸纤维在造纸步骤期间与碳纤维分散体混合，从而消除通常与常规气体扩散介质制造方法相关的酚醛树脂浸渍步骤。 然后将垫固化并碳化以产生气体扩散介质。

摘要： A gas diffusion media and method of making are provided including the formation of a carbon fiber paper which is heated to a carbonization temperature without exceeding a graphitization temperature. The discovery that a final high temperature heat treatment step in the graphitization temperature zone is not necessary to make effective gas diffusion media for PEM fuel cells greatly reduces the cost associated with the high temperature final heat treatment and also allows for the processing of the diffusion media in a roll.
