Description
Summary:Direct methanol fuel cells (DMFCs) are a promising alternative energy technology because they offer high energy conversion efficiency, low emissions of pollutants, and operate at a low temperature while providing the convenient handling and processing of a liquid fuel. However, electrocatalysts with higher activity in room-temperature methanol oxidation are needed for DMFCs to reach commercialization. Pt is the only single-component catalyst that provides good activity for methanol oxidation, but the coproduct CO poisons the catalyst. Therefore Pt-based catalysts with improved methanol oxidation activity and greater resistance to CO poisoning are needed.
