Pd-Co-Mo electrocatalyst for the oxygen reduction reaction in proton exchange membrane fuel cells

Article Abstract:

The catalytic activity of carbon supported Pd-Co-Mo for the oxygen reduction reaction (ORR) in a single cell proton exchange membrane fuel cell (PEMFC) is investigated and compared with the data from commercial Pt catalyst. The investigation reveals that a Pd:Co:Mo atomic ratio of 70:20:10 with a heat treatment temperature of 500 degree Celcius exhibits the highest catalytic activity.

Steady-state dc and impedance investigations of H2/O2 alkaline membrane fuel cells with commercial Pt/C, Ag/C, and Au/C cathodes

Article Abstract:

A report on the performances of H2/O2 metal-cation-free alkaline anion-exchange membrane (AAEM) fuel cells operated with commercially available Au/C and Ag/C cathodes is presented. Results reveal that the oxygen reduction electrokinetics are improved when operating Pt/C cathodes at high pH in AAEM-based fuel cells as compared with operation at low pH.
