    • 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.

    • An anode composition for zinc/air cells comprises a metal binder added to particulate zinc. The metal binder in contact with the particulate zinc is heated to above its melting point. Upon cooling the metal binder solidifies and adheres to the zinc particle surfaces to form agglomerates wherein individual zinc particles are held bound to each other by the metal binder. Gelling agent and electrolyte can then be added to form an anode mixture. The metal binder has a melting point desirably above about 35 DEG C and below the melting point of zinc. A preferred metal binder for the particulate zinc is an alloy of indium and bismuth (In/Bi). Other desisable metal binders, for example, can be an alloy of indium, bismuth and tin (In/Bi/Sn) or alloy of indium and tin (In/Sn) as well as indium metal. Use of the metal binder in the anode mixture improves conductivity of the zinc particles and replaces the need to add mercury to the anode composition.
    • 用于锌/空气电池的阳极组合物包括添加到颗粒状锌中的金属粘合剂。 与颗粒状锌接触的金属粘合剂被加热至其熔点以上。 在冷却时,金属粘合剂固化并粘附到锌颗粒表面以形成附聚物,其中单独的锌颗粒通过金属粘合剂彼此保持结合。 然后可以加入胶凝剂和电解质以形成阳极混合物。 金属粘合剂的熔点理想地高于约35℃并低于锌的熔点。 用于颗粒状锌的优选金属粘合剂是铟和铋的合金(In / Bi)。 例如,其他可以使用铟,铋和锡(In / Bi / Sn)或铟和锡(In / Sn)的合金以及铟金属的合金可以是铟,铋和锡的合金。 在阳极混合物中使用金属粘合剂改善了锌颗粒的导电性,并且替代了向阳极组合物添加汞的需要。
