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 ...
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 ...
