Researchers at the University of California, Santa Barbara designed gated electrode structures to improve the process of electrolysis and electrosynthesis. Here, an electrode of the electrochemical or photo-electrochemical cell is replaced by an appropriate gated electrode that comprises of two electrodes, with the gate electrode biased appropriately with respect to the working electrode. This gated technology aims to reduce overvoltage by enhancing field in the electrolyte near the electrode. Additionally, these electrodes can be made on low cost insulating substrates such as glass or plastic

Background

Hydrogen is expected to become an important energy storage medium for renewable energy sources which have a fickle output due to variability of environmental factors for mobile applications. Cost effective techniques for obtaining hydrogen from water is needed for the hydrogen economy. Several approaches are being explored, but electrolysis is amongst the more attractive schemes for splitting water. Newer, more efficient technology is desired to increase the efficiency and productivity of this process, while maintaining low costs.
