  • Corrosion resistant PEM fuel cell
    Patent number: 6372376
    Abstract: A PEM fuel cell having electrical contact elements comprising a corrosion-susceptible substrate metal coated with an electrically conductive, corrosion-resistant polymer containing a plurality of electrically conductive, corrosion-resistant filler particles. The substrate may have an oxidizable metal first layer (e.g., stainless steel) underlying the polymer coating.
    Type: Grant
    Filed: December 7, 1999
    Date of Patent: April 16, 2002
    Assignee: General Motors Corporation
    Inventors: Matthew Howard Fronk, Rodney Lynn Borup, Jay S. Hulett, Brian K. Brady, Kevin M. Cunningham
  • Fuel cell flooding detection and correction
    Patent number: 6103409
    Abstract: Method and apparatus for monitoring an H.sub.2 -O.sub.2 PEM fuel cells to detect and correct flooding. The pressure drop across a given H.sub.2 or O.sub.2 flow field is monitored and compared to predetermined thresholds of unacceptability. If the pressure drop exists a threshold of unacceptability corrective measures are automatically initiated.
