20140113208 | METHOD AND SYSTEM FOR STABLE DIRECT METHANOL FUEL CELL OPERATION AT VARYING LOADS AND SUB-ZERO TEMPERATURES - 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. | 04-24-2014 |
