Preliminary in situ measurements on 20% PtCo (1:1)/Vulcan XC-72 cathode electrocatalyst at room temperature. EXAFS signals after Pt L3-edge (11564 eV) and Co K-edge (7709 eV). Pt loading: 0.6 mg cm−2; Co loading 0.2 mg cm−2. Integration time: 2 s per point. The dotted lines serve as a guide to the eye. |
