Abstract:
A microfluidic electrolyzer includes a housing having a power source, a sea water reservoir, a downstream microfluidic reactor connected to the reservoir and a collector for storing the separated gases emanating from the microfluidic reactor. The downstream microfluidic reactor includes a substrate, a microchannel embedded with respect to the substrate and providing a water inlet end at one end and a product outlet at the other, and a pair of electrodes. The electrodes are electrically connected with the power source and each electrode has an operative end inserted within the microchannel constituting an anode and a cathode. The cathode and the anode are positioned one ahead of the other, from the water inlet end and maintained in direct contact with the water to generate the oxygen and hydrogen involving electrolysis of the water and in-situ separate pathways of the hydrogen and oxygen free of any mixing with each other.
