Israeli team develops decoupled PEC water-splitting system for centralized production of H2

Green Car Congress

Researchers in Israel have designed a separate-cell photoelectrochemical (PEC) water-splitting system with decoupled hydrogen and oxygen cells for centralized hydrogen production. A paper describing their system is publishedin the journal Joule. The hydrogen cell contains the cathode, and it is physically separated from the oxygen cell.

Kobe team develops method for highly efficient hydrogen production using sunlight, water and hematite

Green Car Congress

A research group led by Associate Professor Takashi Tachikawa of Kobe University’s Molecular Photoscience Research Center has developed a strategy that greatly increases the amount of hydrogen produced from sunlight and water using hematite (??Fe Mesocrystal photoanode formation and photochemical water splitting characteristics.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability. One way this could be achieved is by using photoelectrochemical (PEC) water splitting which directly converts water and sunlight to solar fuel (hydrogen).
