    Abstract: A fuel cell, having improved sealing against leakage, includes a sealant disposed over the peripheral portions a membrane electrode assembly such that the cured sealant penetrates a gas diffusion layer of the membrane electrode assembly. The sealant is applied through liquid injection molding techniques to form cured sealant composition at the peripheral portions of the membrane electrode assembly. The sealant may be thermally cured at low temperatures, for example 130° C. or less, or may be cured at room temperature through the application of actinic radiation. The sealant may be a one-part or a two-part sealant. The sealant includes a polymerizable material, such as a polymerizable monomer, oligomer, telechelic polymer, functional polymer and combinations thereof functionalized with a group selected from epoxy, allyl, vinyl, (meth)acrylate, imide, amide, urethane and combinations thereof.

  • Handling Device
    Publication number: 20080292446
    Abstract: A Bernoulli Effect pick-up device (1) for the handling of products (20) comprises a surface (4) adapted such that gaseous fluid flow across said surface (4) provides a pick-up force to be generated, by the Bernoulli Effect, in a direction towards said surface (4), and a conduit (2) for the supply of the gaseous fluid. The conduit (2) has an outlet opening (5) at the surface (4) and is adapted to supply gaseous fluid in a direction opposed to the pick-up direction. The outlet (5) of the conduit (2) is associated with a deflector (9) for directing gaseous fluid across the surface (4) and preventing direct impingement of the fluid on a product (2) that has been picked-up by the device (1). The product (20) may for example be a slice of a foodstuff, e.g. tomato or hard-boiled egg.

  • Systems and methods for locating a circuit
    Patent number: 7274184
    Abstract: Systems and methods presented herein are generally directed to the location and/or identification of a circuit within a circuit. In one embodiment, a transmitter is configured for inducing a signal upon a circuit (e.g., power lines, communication lines, lighting circuits, etc.) to identify it from other circuit lines. The signal may be induced upon an individual element of the circuit through direct contact. A receiver may receive a radiated component of the signal from a distal point on the circuit to acquire the signal induced thereon and determine a strength of the signal received. Based on the received signal component, the receiver may determine location, configuration, and/or identification of the circuit from which the radiated signal is being received.
