    摘要: An apparatus for microfluidic mixing having a first fluid inlet for a first fluid operatively connected to a first fluid channel. A second fluid inlet is provided for a second fluid operatively connected to a second fluid channel. The second fluid channel operatively intersects the first fluid channel for introduction of the second fluid into the first fluid channel. The first fluid channel has an outlet end remote from that of the first fluid inlet, and at least one contraction intermediate the intersection of the first fluid channel with the second fluid channel and the at least one outlet end, or intermediate the first fluid inlet and the intersection of the first fluid channel with the second fluid channel. A corresponding method is also disclosed.

    摘要: The invention relates to a method for large scale manufacturing of polymeric micro fuel cells using a metallic mold. The method includes creating a Gaussian-shaped channel on a first substrate using a laser; sputtering a metallic seed layer over the first substrate using a first metal; electroplating a second metal over the seed layer to create a negative mold; releasing the negative mold from the first substrate; fabricating a plurality of second substrates, each having a Gaussian-shaped channel, and using the negative mold to fabricate multiple fuel cells. The method provides lower cost and greater flexibility as compared with conventional ablation and etching processes of manufacturing of polymeric micro fuel cells.
