In this microfluidic water electrolysis device, the channels in which oxygen and hydrogen are generated by splitting water are separated by a chemically inert wall (red). The conduction of protons from one channel to the other, which is required for continuous operation, occurs via a Nafion® membrane cap (blue).May 2015Science Highlights
