摘要： A method and device for the pumping of liquids utilizes the directional growth and elimination of gaseous vesicles or bubbles to provide the motive or pumping force. In one embodiment, the pumping device is a microfluidic pumping mechanism having a channel, a bubble generator for generating a plurality of bubbles within the channel, and a venting membrane disposed over a portion of the channel downstream of the bubble generator. A one-way valve or directional resistance feature is positioned upstream of the bubble generator to introduce directional transport of bubbles within the channel. The method and device may be integrated into micro fuel cells with organic liquid fuel such that liberated gaseous bubbles may be utilized to deliver fresh fuel or circulate reusable fuel without any power-consuming components.
