摘要： A fuel cell includes a membrane electrode assembly (MEA), a fuel delivery system distributing fuel to an anode side of the MEA, and a flow distributor delivering an oxidizer to a cathode side of the MEA. The flow distributor includes at least one serpentine channel through which the oxidizer is delivered to the cathode side of the MEA. Each portion of the serpentine channel delivers oxidizer to a portion of the cathode side of the MEA in contact, directly or through a porous diffuser, with the channel portion. The channel portion transfers water with the portion of the MEA in contact with the channel portion and also transfers water between adjacent channel portions via a water-permeable, gas impermeable material that defines at least a portion of the channel.
