    • A fuel cell includes a membrane electrode assembly (MEA) (250), a fuel delivery system (210) distributing fuel to an anode side of the MEA (250), and a flow distributor (280) delivering an oxidizer to a cathode side of the MEA (250). The flow distributor (280) includes at least one serpentine channel (285) through which the oxidizer is delivered to the cathode side of the MEA (250). Each portion of the serpentine channel (285) delivers oxidizer to a portion of the cathode side of the MEA (250) in contact, directly or through a porous diffuser, with the channel portion (285). The channel portion transfers water with the portion of the MEA (250) in contact with the channel portion (285) and also transfers water between adjacent channel portions via a water-permeable, gas impermeable material (282) that defines at least a portion of the channel.
    • 燃料电池包括膜电极组件(MEA)(250),将燃料分配到MEA(250)的阳极侧的燃料输送系统(210)和将氧化剂输送到阴极侧的流量分配器 MEA(250)。 流量分配器(280)包括至少一个蛇形通道(285),通过该至少一个蛇形通道将氧化剂输送到MEA(250)的阴极侧。 蛇形通道(285)的每个部分将氧化剂直接地或通过多孔扩散器与通道部分(285)接触地接触MEA(250)的阴极侧的一部分。 通道部分将水与MEA(250)的与通道部分(285)接触的部分进行转移,并且还经由可透水的不透气材料(282)在相邻通道部分之间转移水分,该材料限定了至少一部分 这个频道。
