Researchers from Tokyo Tech have identified hexagonal perovskite-related Ba5R2Al2SnO13 oxides (R = rare earth metal) as ...

A new approach to elucidate the operation and control of Polymer Electrolyte Membrane (PEM) fuel cells is being developed. A global reactor engineering approach is applied to PEM fuel cells to ...

All fuel cells have the same basic configuration, an electrolyte and two electrodes, but there are different types of fuel cells, based mainly on what kind of electrolyte they use. Many ...

Researchers at the Korea Institute of Science and Technology recently designed a new polymer electrolyte membrane (PEM) for fuel cells that can operate at temperatures above 200 °C and up to ...

Electrochemical reactions -- chemical transformations that are caused by or accompanied by the flow of electric currents -- are the basis of batteries, fuel cells, electrolysis, and solar-powered ...

According to [Charles Q. Choi], a new study indicates that grooves in the hydrogen fuel cells used to power vehicles can improve their performance by up to 50%. Fuel cells are like batteries ...

Rapid electrochemical method enhances solid oxide fuel cell electrodes, reducing polarization resistance and boosting peak ...

She is particularly interested in both fuel cell electricity and electrolytic hydrogen production. Her recent work has explored the modeling and experimental validation of mass and thermal dynamics in ...

The electrons create an electric current, while the protons migrate through the electrolyte to the cathode, where they react with oxygen to form water. Most fuel cells are solid oxide fuel cells ...

Hydrogen fuel cells are highly efficient. They use hydrogen and oxygen to produce electricity and heat. Electrolysers reverse this process. They split water into hydrogen and oxygen with the help of ...
