The interactions between phosphorous acid and the platinum catalyst in high-temperature PEM fuel cells are more complex than previously assumed. Experiments at BESSY II with tender X-rays have decoded ...

(Phys.org)—As scientists look for alternative energy sources, fuel cells that operate in a basic environment have garnered much attention. Typically fuel cells require an expensive catalyst, such as ...

Electrocatalytic oxidation in alcohol fuel cells converts the chemical energy of small organic molecules directly into electricity by means of surface reactions at a catalyst–electrolyte interface. In ...

Chemists have developed the most potent homogeneous catalyst known for water oxidation, considered a crucial component for generating clean hydrogen fuel using only water and sunlight. Emory ...

The illustration shows four different oxidation pathways (1-4) of aqueous phosphoric acid (H 3 PO 3), which could be elucidated by XANES at BESSY II. All these reactions depend on the humidity present ...
