  • Selectively activated electrochemical cell system
    Patent number: 6933703
    Abstract: A power generating system is described including a plurality of electrochemical cells. The cells are generally arranged in sections that are selectively activated individually or in combination to produce power from selected cell sections. A method of generating power is also described. A first group of one or more electrochemical cells of an array of cells are selectively activated based on requirement of an associated load. The system switches to a second group of one or more electrochemical cells of the array when the first group is discharged.
    Type: Grant
    Filed: January 23, 2004
    Date of Patent: August 23, 2005
    Assignee: eVionyx, Inc.
    Inventors: Donald Dubac, Michael Glover, Haresh P. Kamath
