Fuel cells have long promised a clean energy future in which hydrogen replaces fossil fuels in cars, trucks, and even power ...

Proton exchange membrane fuel cells (PEMFCs) hold promise as a replacement for fossil fueled engines in heavy-duty vehicles. Reducing the platinum content in catalysts is pivotal for scaling up in ...

Electrochemical devices like batteries and fuel cells help power our modern lives. These devices traditionally contain a liquid electrolyte sandwiched between solid electrodes, and can generate ...

Current electrochemical theory does not adequately describe realistic platinum electrodes. Scientists at Leiden University have now, for the first time, mapped the influence of imperfect platinum ...

Isolated platinum atoms keep conductive glass transparent while driving hydrogen evolution at near-bulk-platinum rates in acidic, neutral and alkaline media. (Nanowerk Spotlight) Only the outermost ...
