Korea-led team develops hybrid solid oxide electrolysis cell for efficient production of #H2 #SOEC

Korea-led team develops hybrid solid oxide electrolysis cell for efficient production of H2 27 December 2017 Solid oxide electrolysis cell (SOEC) has the potential to be cost-effective, environmentally friendly, and highly efficient for the production of hydrogen from water. There are two types of SOECs, based on the electrolyte materials: oxygen ion conducting SOECs (oxygen-SOECs) and proton conducting SOECs (proton-SOECs). Researchers in South Korea, with colleagues at Georgia Tech, have now developed an SOEC based on a mixed-ion conductor that can transport both oxygen ions and protons at the same time; they call it a “Hybrid-SOEC”. In a paper in the journal Nano Energy , the researchers reported that the hydrogen yield from their Hybrid-SOEC was 1.9 L per hour at a cell voltage of 1.5 V at 700 °C—four times higher hydrogen production efficiency of the existing high-eff...
