Abstract
|
Fuel cells can directly convert chemical energy
into electric energy with both high conversion
efficiency and power density. Among many
factors affecting the chemical−electrical energy
conversion, oxygen reduction reaction (ORR) on
the cathode is the pivot in fuel cell. This reaction
is a kinetically slow process in comparison with
the hydrogen oxidation taking place in the anode,
So, almost the totality of the current research and
development focuses on improving the cathode
catalysts and electrodes]1-3[. Up to now, Pt and
Pt-based alloys are found to have high activity for
ORR and considered to be the most efficient
Catalysts. However, the high cost, poor durability
and CO deacti-vation of Pt-based alloys in FCs
are the major drawbacks hindering their
widespread commercial applications. Hence,
searching novel and high performance catalysts,
such as low cost, high energy conversion
efficiency, high durability, etc.
