摘要： Corrosion of the carbon catalyst support may occur at both the anode and cathode catalyst layers within an electrochemical fuel cell. Such corrosion may lead to reduced performance and/or decreased lifetimes of the fuel cell. Nevertheless, carbon supports have many desirable properties as catalyst supports including high surface area, high electrical conductivity, good porosity and density. To reduce or eliminate corrosion of the carbon catalyst support, the carbon support may have a metal surface treatment and, in particular, a metal carbide surface treatment. Suitable metal carbides include titanium, tungsten and molybdenum. In this manner, the metal carbide surface treatment protects the underlying carbon support from corrosion while maintaining the desirable characteristics of the carbon support.

摘要： A power converter architecture interleaves full bridge converters to alleviate thermal management problems in high current applications, and may, for example, double the output power capability while reducing parts count and costs. For example, one phase of a three phase inverter is shared between two transformers, which provide power to a rectifier such as a current doubler rectifier to provide two full bridge DC/DC converters with three rather than four high voltage inverter legs.

摘要： A membrane electrode assembly has two gas diffusion layers, two catalyst layers and an ion-exchange membrane interposed therebetween wherein the ion-exchange membrane is cast from a sulphonated polyether ketone/sulfone ionomer. Specifically, the ionomer can be represented as A-B-C wherein A is B is and C is Further x, y, z represent the mole ratios of each moiety in the ionomer such that x is between 0.25 and 0.40; y is between 0.01 and 0.26; and z is between 0.40 and 0.67. Melt viscosity of the corresponding base polymer also affects performance in the fuel cell, particularly at values over 0.4 kNsm -2 as measured at 400 °C, 1000 s -1 . In preparing the membrane electrode assembly, the catalyst layers may be coated directly on the membrane and then bonded with two gas diffusion layers.

摘要： An electric power generation system has a multiple jet ejector assembly for recirculating an exhaust stream. The system includes a fuel cell stack having a reactant stream inlet, a reactant stream outlet and at least one fuel cell. A pressurized reactant supply provides a reactant to the multiple jet ejector assembly. The multiple jet ejector assembly includes two motive flow inlets, one suction inlet, fluidly connected to the reactant stream outlet to receive a recirculated flow from the fuel cell stack, and one discharge outlet, fluidly connected to the reactant stream inlet to provide an inlet stream to the fuel cell stack. A pressure regulator is interposed between the pressurized reactant supply and the two motive flow inlets of the multiple jet ejector assembly. A first solenoid valve is interposed between the first motive flow inlet and the regulator. A second solenoid valve is interposed between the second motive flow inlet and the regulator. A by-pass line connects the pressurized reactant supply to the second motive flow inlet. A by-pass solenoid valve is interposed in the bypass line between the pressurized reactant supply and the second motive flow inlet. During low-load operating conditions, the second solenoid valve is open and the first and by-pass solenoid valves are closed, so that pressurized reactant, controlled by the regulator, is directed to the second motive flow inlet. During high-load operating conditions, the second solenoid valve is closed and the first and by-pass solenoid valves are open, so that pressurized reactant, controlled by the regulator, is directed to the first motive flow inlet and pressurized reactant, not controlled by the regulator, is directed to the second motive flow inlet.

摘要： An alternating current (AC) bus malfunction detection and protection module monitors an AC voltage that is provided on a bus by a house keeping power supply of a power system. If the AC voltage on the bus falls below a first level, the module provides a delay before power inverter switching is disabled. If the AC voltage on the bus falls below a second level, the module disables the power inverter switching without delay.

摘要： A membrane electrode assembly comprises an edge seal member, the edge seal member having a first compressive surface and an opposing second compressive surface wherein the first compressive surface comprises a seal protrusion and the opposing second compressive comprises an inner and outer seal protrusion. The seal protrusion on the first compressive surface is positioned asymmetrically in relation to the inner and outer seal protrusions on the second compressive surface such that the centerline of the seal protrusion on the first compressive surface is positioned between the centerline of the inner seal protrusion and the centerline of the outer seal protrusion on the second compressive surface. The seal protrusions may be shaped such that the base is wide and narrows toward a contacting end thereof, wherein the contacting end is in contact with a surface of a flow field plate. The geometry and positions of the seal protrusions can be adjusted to optimize the contact pressure on the edge seal member and contacting points thereof.

摘要： Improvements in startup time for an electrochemical fuel cell system from freezing and sub-freezing temperatures are obtained by utilizing an insulated fuel cell stack in combination with an thermal control subsystem. Temperature of the insulated electrochemical fuel cell stack, as well as temperature of the ambient environment, are monitored and a heating fluid is heated by thermal transfer with the environment under appropriate thermal conditions. The heated fluid is then passed to the insulated fuel cell in order to increase the temperature of the same, typically to a temperature at or near the temperature of the ambient environment. In this manner, ambient heat from the environment is utilized to increase the temperature of the insulated fuel cell stack, thus improving conditions for subsequent cold start of the insulated fuel cell stack.
