  • Seal for solid polymer electrolyte fuel cell
    Patent number: 9240598
    Abstract: In solid polymer fuel cells employing framed membrane electrode assemblies, a conventional anode compliant seal is employed in combination with a cathode non-compliant seal to provide for a thinner fuel cell design, particularly in the context of a fuel cell stack. This approach is particularly suitable for fuel cells operating at low pressure.
    Type: Grant
    Filed: August 6, 2014
    Date of Patent: January 19, 2016
    Assignee: Ballard Power Systems Inc.
    Inventors: Keith M. Martin, Samira Barakat, Emerson R. Gallagher

  • Variably printed tape and system for printing and applying tape onto surfaces
    Publication number: 20030124345
    Abstract: An apparatus for printing variable information on a tape to form a tape segment, cutting the tape segment to form a tag, and applying the tag onto an object includes a printer for printing information onto the tape segment. A controller controls the printer in response to input to vary the information printed onto the tape. The printed tape segment is transported to a location for application onto the object and is cut.

    Patent number: 6432528
    Abstract: An apparatus for printing variable information on a tape to form a tape segment, cutting the tape segment to form a tag, and applying the tag onto an object includes a printer for printing information onto the tape segment. A controller controls the printer in response to input to vary the information printed onto the tape. The printed tape segment is transported to a location for application onto the object and is cut. An adhesive tape can have variable information printed on it and can be applied onto an object. The tape includes a backing layer and an adhesive layer on the first side of the backing layer. At least one of the backing layer and the adhesive layer are colored to yield a tape opacity of greater than 60. The tape can have a scan rating of at least C when applied on a black background and an opacity of at least 65.
