Artificial Photosynthesis Microfluidic Test-Bed (image) DOE/Lawrence Berkeley National Laboratory Caption In this microfluidic test-bed, a chemically inert wall (red) separates anode from cathode and the channels in which O2 and H2 are generated by splitting water. Protons (H+) are conducted from one channel to the other via a membrane cap (Nafion®) that also prevents the intermixing of the O2 and H2 product streams.
