  • Method and system for stable direct methanol fuel cell operation at varying loads and sub-zero temperatures
    Patent number: 9350032
    Abstract: Methods and systems for operation of direct methanol fuel cell (DFMC) systems with enhanced flexibility within a wide range of electrical loads as well as no external load are provided. With these methods and systems, the fuel cell operates at low power in a non shut-down state in a fully controlled manner thus allowing the fuel cell to withstand frost conditions and to maintain optimal ancillary battery capacity.
    Type: Grant
    Filed: January 30, 2012
    Date of Patent: May 24, 2016
    Assignee: IRD FUEL CELLS A/S
    Inventors: Visti Andresen, Jacob Lindner Bonde, Joergen S. Lundsgaard, Madeleine Odgaard
