A system and method for controlling or otherwise effectively parameterizing the
transport of dissolved, retained and/or exhausted gaseous byproducts generated
in the operation of a fuel cell device comprises a gas permeable membrane (320)
for substantially in-line, gravity-independent partitioning of, for example, carbon
dioxide (710) in a DMFC device (700). Various features and parameters
of the present invention may be suitably adapted to optimize the gas transport
function for any specific fuel cell design. The present invention provides improved
control of the rate of removal of gaseous byproducts from a fuel cell fuel solution
in addition to improved application of fuel cell technology to power inter alia
portable electronic devices.
