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.

U Oregon team advances effectiveness of catalytic water dissociation in bipolar membranes

Green Car Congress

Researchers at the University of Oregon have advanced the effectiveness of the catalytic water dissociation reaction in bipolar membranes. The technology behind bipolar membranes, which are layered ion-exchange polymers sandwiching a water dissociation catalyst layer, emerged in the 1950s. —Oener et al.

Toshiba’s new large-scale production technology for electrolysis electrodes cuts iridium use to 1/10

Green Car Congress

Toshiba Corporation has developed large-scale production technology for electrolysis electrodes that realize high level efficiency in Power to Gas (P2G) technology while reducing the use of iridium, one of the world’s rarest precious metals, to 1/10. Structures of Oxide Nanosheet and MEA developed by Toshiba.

New system for more efficient CO2 electrolysis to hydrocarbon products

Green Car Congress

The researchers combined a copper electrocatalyst with an ionomer [polymers that conduct ions and water] assembly that intersperses sulfonate-lined paths for the H 2 O with fluorocarbon channels for the CO 2. Here, we present a catalyst:ionomer bulk heterojunction (CIBH) architecture that decouples gas, ion, and electron transport.

MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

The findings could spur progress on developing a variety of materials and designs for electrochemical carbon dioxide conversion systems. For the latter, two main contributions are distinguished: gas depletion due to CO 2 consumption and ion generation in areas close to the electrocatalyst surface. —Soto et al.
