Techniques for reproducible and spatially resolved in situ measurements of the electrochemically active surface area (ECSA) are introduced. Moreover, two CL degradation mitigation strategies are discussed. The first strategy is based on intentionally increased CO partial pressures at the fuel electrode ...

(C) ATR-FTIR spectra. (D and E) Synchrotron-based XPS spectra for carbon 1s (D) and oxygen 1s (E). (F) The surface oxygen to carbon ratio for three carbon samples evaluated; C1, C2, and C3. To investigate the impact of these carbon supports on fuel cell performance, we prepared ...
The combination of ultrasound and microreactors for the synthesis of nanomaterials is becoming increasingly popular, but effectively altering the ultrasonic field at the microscale to control the crystallization process remains a challenge. Herein, we investigated numerically and experimentally the effects of...
49 It can be seen from Fourier transform infrared (FTIR) spectroscopy that the original characteristic peak of the N-H bond (3,032 cm−1) disappears after the metal doping coupling with the maintenance of characteristic peak for C = N (1,629 cm−1), which proves successful doping of ...
