Comparative study of the corrosion behavior of platinum-based nanosized cathodic catalysts for fuel cells

A review of platinum-based catalyst layer degradation in proton exchange membrane fuel cells

“…Co, Cr, Fe, Ni and Pd contained Pt alloys have been synthesized using several preparation methods and have been investigated in PEM fuel cells. Tarasevich et al [69] compared the durability of PtCo/C and Pt/C catalysts by corrosion tests carried out in a 0.5 M H 2 SO 4 solution. The temperature of the solution was periodically increased up to 60 • C and the testing was performed in the presence of 10% H 2 O 2 or air bubbling.…”

Development of platinum-free catalyst and catalyst with low platinum content for cathodic oxygen reduction in acidic electrolytes

“…However, Pt is dissolved in model conditions and during FC testing [12,21], which results in a decrease in performance and membrane degradation. Some data are presented in Fig.…”

“…Such a shift of the maximum was observed in the case of PtCo/C alloy (Fig. 2b) [12]. The energy values of the components for the Co2p 3/2 band are 779.6, 780.6 and 782.4 eV.…”

“…The employment of the high-temperature synthesis method and application of Co precursors when choosing the optimum Pt(Pd) : Co ratio allowed synthesis of a system with a high alloy formation level [12,14]. Structural characteristics of PdCo/C are presented in Sect.…”

“…Earlier, PtCo (1 : 1) catalyst (7.3 wt.% Pt, supported on XC 72) was synthesized using the high-temperature method [12]. The PtCo/C system was modified by phosphorus and sulfur.…”
