Korea’s Daegu Gyeongbuk Institute of Science and Technology (DGIST) researchers have fabricated nano-sized catalysts that could improve the performance and production of clean energy fuel cells. The team’s study results have been published in the journal of Applied Catalysis B: Environmental. Polymer electrolyte membrane fuel cells (PEMFCs) transform the chemical energy produced during a reaction […]

DOE/Argonne National Laboratory scientists have identified a new catalyst that uses only about a quarter as much platinum as current technology by maximizing the effectiveness of the available platinum. The Argonne chemists have published their study results in the journal Science. Platinum is a precious metal more rare than silver or gold. Renowned in the […]

Ruhr-University Bochum researchers have combined two concepts that make a biofuel cell as efficient as precious metal catalysts. Fuel cells that work with the enzyme hydrogenase are, in principle, just as efficient as those that contain the expensive precious metal platinum as a catalyst. However, the enzymes need an aqueous environment, which makes it difficult […]

There’s a new cell that runs on cheap methane fuel at temperatures comparable to automobile engines. The low operating temperature slashes materials costs. The new fuel cell may change a perception they are not particularly known for their practicality and affordability. Though the cell is in the lab, it has high potential to someday electrically […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Ruhr-University Bochum researchers have developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. These enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable when they come into contact with oxygen. They are therefore not yet suitable for technological applications. The new protective mechanism is […]
