Abstract
Apparatus and methods for regulating methanol concentration in a direct methanol fuel cell system are provided. The apparatus and methods do not require a methanol concentration sensor. One or more operating characteristics of the fuel cell, such as the potential across the load, open circuit potential or potential at the anode proximate to the end of the fuel flow path, are used to actively control the methanol concentration.
