  • Pressure sensor for use in fuel cell systems
    Patent number: 8347737
    Abstract: A pressure sensor for measuring a pressure of a fluid in fluid flow path of a fuel cell system is disclosed. The pressure sensor includes a housing provided with a communication path formed between the fluid flow path and an interior of the housing, the communication path having a hydrophobic feature to militate against a formation and an accumulation of an undesired material within the pressure sensor.
    Type: Grant
    Filed: January 10, 2011
    Date of Patent: January 8, 2013
    Assignee: GM Global Technology Operations LLC
    Inventors: Jon P. Owejan, Mark T. Schluentz, Steven L. Piedmont
