摘要： A fuel cell with a gas diffusion media having a hydrophobic layer adjacent a flow field plate and a hydrophilic layer adjacent the membrane electrode assembly of the fuel cell. The two layers enable balanced humidification of reactant gas along with a basis for managing capillary water addition into the gas diffusion media. The combination of balanced moisture flux (via the hydrophobic layer) and the retention of water (via the hydrophilic layer) for humidifying reactant gas sustains hydration of the proton exchange membrane while preserving the catalyst at full activity.

摘要： An electrode-electrolyte unit for a fuel cell which prevents the permeation of the fuel used or the permeation of water through the electrolyte layer. An electrolyte is subdivided into two electrolyte layers with a barrier layer disposed between them. The barrier layer is permeable only to protons and may be coated with a catalytically active porous layer having a high effective surface area. A porous layer on the side of the unit facing the cathode increases the electrochemically active surface area and a porous layer on the side of the unit facing the anode ensures that a sufficient amount of hydrogen is dissolved. The fuel used can be hydrogen or methanol and suitable electrolytes include membranes or other solid or liquid electrolytes.
摘要翻译：一种用于燃料电池的电极 - 电解质单元，其防止所使用的燃料渗透或渗透通过电解质层。电解质被细分为两个电解质层，其间设置有阻挡层。阻挡层仅可渗透质子，并且可以涂覆有具有高有效表面积的催化活性多孔层。面向阴极的单元侧的多孔层增加了电化学活性表面积，并且面向阳极的单元侧面上的多孔层确保了足够量的氢溶解。使用的燃料可以是氢气或甲醇，合适的电解质包括膜或其它固体或液体电解质。
