Stretching oxides to modulate electrochemical properties

Solid oxide fuel cells and solid oxide electrolysis cells hold the promise of highly efficient energy conversion, with lower pollution, to meet increasing global energy demands. But these devices need good catalysis to speed ...

Chromium's bonding angles let oxygen move quickly

By taking advantage of the natural tendency of chromium atoms to avoid certain bonding environments, scientists at DOE's Pacific Northwest National Laboratory have generated a material that allows oxygen to move through it ...

Efficient production process for coveted nanocrystals

A formation mechanism of nanocrystalline cerium dioxide (CeO2), a versatile nanomaterial, has been unveiled by scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the University of New South Wales in Sydney, ...

X-rays reveal fuel cells in action

(Phys.org) —Wouldn't it be great to have a magical "energy box" that could convert a wide array of fuels to electricity with high efficiency and lower emissions? Solid oxide fuel cells (SOFCs) show significant promise. ...

Lab startup brings fuel cells to the developing world

(Phys.org) —In some parts of the developing world, people may live in homes without electricity or toilets or running water but yet they own cell phones. To charge those phones, they may have to walk for miles to reach ...

Coal gasification demonstrated

DOE's National Energy Technology Laboratory (NETL) has developed a molten catalytic process for converting coal into a synthesis gas consisting of roughly 20% methane and 80% hydrogen using alkali hydroxides as both gasification ...

Researchers probe invisible vacancies in fuel cell materials

(Phys.org) -- Knowing the position of missing oxygen atoms could be the key to cheaper solid oxide fuel cells with longer lifetimes. New microscopy research from the Department of Energy's Oak Ridge National Laboratory is ...

Fuel cells operating directly on ethanol

(Phys.org) -- Researchers at the Center for Energy Research at UC San Diego recently demonstrated the best performance for solid oxide fuel cells (SOFCs) operating directly on ethanol without external reformation. The work ...
