    摘要： In one example, a fuel cell utilizes a non-carbonized, non-graphitized porous polymer water transport plate having a water permeability of less than 30×10−17 m2. The water transport plate is part of a fuel cell that employs an evaporative cooling loop. In one example, the water transport plate has a bubble pressure of less than 5 psig. The water transport plate is less costly and easier to manufacture.

    摘要： A vehicle (150) includes a fuel cell stack (151) started when the stack is below freezing, by connection (158) to the vehicle propulsion system (159) within a few seconds of starting the flow of fuel (179) and oxidant (173), or when open circuit voltage (155, 156) is detected. The fuel is in excess of stochiometry requirement and the oxidant is in excess of at least twice stochiometric requirement, either may be at about atmospheric pressure or at 4 kPa (0.6 psi) or more above the pressure of any water in said water passages, and either may be below freezing. Water transport plates (84, 86, 88, 89) have water passages connected to a water circulation loop (170) including a reservoir (164) having an auxiliary heater (161) connected (160) to the stack. Warming of cell stack materials and ice in the water transport plates, heat of fusion of melting ice, warming of melted water, and evaporative cooling of water melted in the water transport plates keep the fuel cell cool until liquid coolant can be circulated.

    摘要： A plurality of fuel cell stacks (8, 8a, 9, 9a) have their cathode ends (11, 12) contiguous with either a common current collector (15a–15d) or respective current collectors (15a, 15b) which may be separated by electrical isolation (27a, 27b). The cathode-to-cathode relationship protects the cathode of each of the stacks from cold ambient environments, thereby permitting improved cold starts and mitigation of performance loss as a result of cold starts as well as freeze/thaw cycles. Heaters (30, 30a–30d) may be provided in current collectors, or in or between electrical isolation. Four stacks may share one current collector, or each may have its own current collector.

    摘要： A fuel cell includes a membrane electrode assembly comprised of a membrane sandwiched between anode and cathode catalyst structures. An anode separator plate and a cathode separator plate are arranged adjacent to the membrane electrode assembly opposite from one another. The anode and cathode separator plates include opposing sides in which one of the opposing sides of the anode and cathode respectively have fuel and oxidant flow fields in communication with the membrane. The anode separator plate is a structure having a first water permeability and is configured to permit passage of water between its opposing sides and with its flow field, and the cathode separator plate comprises a structure having a second water permeability less than the first water permeability of the anode separator plate. In one example, the anode is provided by a porous separator plate, and the cathode is provided by a non-porous, or solid, plate.
