Abstract: An exemplary method for making a micropump device is disclosed as providing inter alia a substrate (300), an inlet opening (310), and outlet opening (340), a pump chamber (370) and flapper valves (350, 360). The fluid inlet channel (310) is generally configured to flow a fluid through/around the inlet opening flapper valve (350). The outlet opening flapper valve (360) generally provides means for preventing or otherwise decreasing the incidence of outlet fluid re-entering either the pumping cavity (370) and/or the fluid inlet channel (310). Accordingly, the reduction of backflow generally tends to enhance overall pumping efficiency. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve micropump operation in any microfluidic application. Exemplary embodiments of the present invention representatively provide for substantially self-priming gas/liquid micropumps that may be readily integrated with existing portable ceramic technologies for the improvement of device package form factors, weights and other manufacturing and/or device performance metrics.

Abstract: 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.
