Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

NOVEMBER 24, 2014

Researchers from Ulsan National Institute of Science and Technology (UNIST) in Korea and Karlsruher Institute of Technology in Germany have developed a novel energy conversion and storage system using seawater as a cathode. Similarly, sodium has recently attracted attention as a replacement for lithium in alkali-metal-air batteries.

Our concept has the following advantages: Compared to carbon dioxide, solid bicarbonates are easy to handle and highly soluble in aqueous media (96 g L -1 NaHCO 3. Most importantly, after full conversion of the formate, the bicarbonate solution may be recharged with hydrogen to close the cycle. at 20 °C in H 2 O).
