Abstract
A direct methanol fuel cell (DMFC) system in which, in response to changes in the output power level of the cell, the concentration of methanol supplied to the anode is actively regulated. As a result, cross-over of methanol through the cell's membrane electrolyte is minimized, and operating efficiency is maintained over a wide dynamic range of output power levels.
