Patents by Inventor Jeremy Stephen Matcham

Jeremy Stephen Matcham has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Water management in fuel cells
    Patent number: 8609288
    Abstract: An electrochemical fuel cell having an anode, an ion transfer membrane and a cathode has liquid water delivered to the fluid flow channels within the cathode so as to maintain a relative humidity of 100% throughout the fluid flow channels. A calibration method and apparatus is described for determining an optimum quantity or range of quantities of liquid water to be delivered to the cathode fluid flow channels under varying operating conditions. An operating method and apparatus is described that ensures an optimum quantity of liquid water is delivered to the cathode fluid flow channels under varying operating conditions.
    Type: Grant

  • Fuel utilisation in electrochemical fuel cells
    Patent number: 8431280
    Abstract: A fuel cell assembly provides for the delivery of fluid into a channel of a fluid flow field plate in alternating flow directions through the channel for delivery of the fluid to a membrane-electrode assembly. The fuel cell includes a fluid flow field plate having a channel for delivery of fluid to a membrane-electrode assembly, the channel having a first inlet/outlet port communicating therewith and a second inlet/outlet port communicating therewith; and a fluid delivery system connected to the fluid flow field plate adapted for bi-directional delivery of fluid into the channel of the fluid flow field plate.
