    摘要: A model uses various operating characteristics of a fuel cell to predict the relative humidity profile that is occurring within the fuel cell as a function of the reaction progress. The model is used to predict the relative humidity profile that will occur in response to changes to one or more of the operating characteristics of the fuel cell. A high frequency resistance of the fuel cell can also be used as a measure that is indicative of the humidity within the fuel cell. The model and/or the high frequency resistance can be used in a closed-loop feedback system to control the operation of the fuel cell to maintain the humidification of the MEA and fuel cells within a desired range to achieve a desired fuel cell performance.

    摘要: A one-piece combination radiator tank and oil cooler for an automotive vehicle comprises a molded polymer structure of double wall construction such that the space between the walls is an oil cooler reservoir which shares a common wall with the coolant reservoir of the radiator tank. The heat from the oil reservoir is transferred to the coolant reservoir. Heat transfer across the common wall is enhanced by using high surface area shapes and by using surface features that promote good heat transfer. The inlet and outlet fittings are also molded polymer. The whole assembly is molded as one piece or as a very few pieces which are bonded together.

    摘要: A bipolar plate includes angled facets oriented to form V-shaped projections on the plate edge. Liquid leaving the reactant channels is drawn back into the V-shaped grooves of the projections, leaving no liquid to obstruct the channel exit openings. The bipolar plate includes one portion of the bipolar plate offset from another portion of the bipolar plate so as to expose the reactant channels. The liquid is drawn toward the end portions of the reactant channels by capillary forces, while the gas flows can exit near the beginning of the offset portion. A fuel cell stack includes angled facets that are rotated to lie in the plane of the bipolar plate edges. The edges are chamfered so the channel exit openings of the reactant channels are at the tip portions thereof, thus allowing the liquid to flow away from the channel exit openings and the gas to exit freely.
