| titleOfInvention | Power management for fuel cell assembly |
| abstract | The invention provides a method and a system of power management suitable for use in a range extender for an electric vehicle. The range extender comprises a primary circuit with a fuel cell assembly ( 10) comprising a plurality of fuel cell segments (14), each segment comprising a plurality of in-plane fuel cells (12) connected in series on a support (16). A hydrogen feed means is provided comprising a valve (20) for each segment (14) for controlling flow into each segment. A secondary circuit comprising a plurality of DC-DC converters converts the voltage to a predetermined value. A power circuit comprising an inverter is arranged to receive the output from the secondary circuit and for providing a threephase voltage. A control unit comprises circuitry configured to implement the method. The method comprises monitoring the voltage of each individual fuel cell in the assembly, and recording deviations from a set value of said voltage. If a voltage of one of said in-plane fuel cells (12) deviates from said set value by a predetermined amount, closing the valve (20) for the segment (14) in question where said cell (12) is located, thereby shutting off said segment (14) from power generation. |
