Abstract
Continuing growth in global energy demand has fueled concern about energy
security and environmental sustainability. Among the various innovative energy
technologies that have been developed in recent years, the direct methanol fuel
cell (DMFC) is one of the most promising for the near future.
Simple
construction, compact design, high energy density and relatively high
energy-conversion efficiency give the DMFC an advantage over other promising
power sources in terms of portability. Unfortunately, poor performance makes
the transitioning of DMFCs into commercially successful products problematic. Low
activity, poor durability and reliability and an expensive anode and cathode are
additional obstacles to the application of DMFCs. Authors review recent
progress in the development of anode and cathode catalysts for DMFCs.
They first discuss recent developments in the synthesis of single-,
double-, and multiple-component catalysts and new catalyst supports for anode
electrodes. Their next section describes the chemical approaches used to make
alloys and composite catalysts, with the goal of increasing their activity,
reliability and durability for the methanol oxidation reaction. They conclude
with a discussion of exciting new research that pushes the development of
single-, double-, and multiple-component catalysts and new catalyst supports
for cathode electrodes.
