New solid polymer electrolyte outperforms Nafion; novel polymer folding

Green Car Congress

Researchers, led by a team from the University of Pennsylvania, have used a polymer-folding mechanism to develop a new and versatile kind of solid polymer electrolyte (SPE) that currently offers proton conductivity faster than Nafion by a factor of 2, the benchmark for fuel cell membranes.

Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The current flows to the catalysts that turn water into hydrogen and oxygen, with a sunlight-to-hydrogen efficiency as high as 6.7%. It utilizes water and sunlight to get chemical fuels. Illustration by Jia Liang.

Eos Energy launches $500M Project AMAZE with $398.6M conditional loan guarantee from DOE; long-term zinc-based storage

Green Car Congress

The streamlined Eos Z3 battery module design features an aqueous electrolyte, bipolar electrodes, and a polymer casing. The bipolar structure simplifies internal battery connections to reduce internal resistance and improve round-trip efficiency. Conductive plastic anodes (-) and carbon-felt cathodes (+) make up the Z3 electrodes.

NPL novel reference electrode shows that cathode, not anode, is source of potential decay in PEM water electrolyzers

Green Car Congress

Scientists from the National Physical Laboratory (NPL) in the UK have developed a novel reference electrode for polymer electrolyte membrane water electrolyzers (PEMWEs) and used it to measure the electrochemical surface area (ECSA) of Pt catalysts in situ for the first time.

Harvard researchers develop tough, self-healing rubber

Green Car Congress

Self-healing materials aren’t new—researchers at SEAS have developed self-healing hydrogels, which rely on water to incorporate reversible bonds that can promote healing. Rubber is made of polymers often connected by permanent, covalent bonds. While these bonds are incredibly strong, they will never reconnect once broken.

Fraunhofer IWKS starts project BReCycle on efficient recycling of fuel cells

Green Car Congress

Fuel cells, especially polymer electrolyte membrane fuel cells (PEMFC), are already used in hydrogen-powered automobiles. General recycling processes for precious metals that are currently in use are also designed for these metals, in which polymer electrolyte membrane fuel cells are currently largely processed.

Twelve produces first batch of E-Jet fuel from CO2 electrolysis; partnership with USAF; electrifying fuel, not planes

Green Car Congress

Twelve has developed an efficient polymer-electrolyte membrane (PEM) CO 2 electrolyzer that uses proprietary CO 2 -reducing catalysts to split CO 2 with just water and renewable electricity as inputs, syngas (CO and hydrogen) as the output, and pure oxygen as the only byproduct. —Twelve Co-Founder and CEO Nicholas Flanders.
