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.
