Synthesis and electrochemical studies of ptgraphene and platinum bimetallic electrocatalysts for polymer electrolyte membrane fuel cell and direct methanol fuel cell

Abstract

Growing energy demands have stimulated intense research on newlinealternative energy conversion systems especially fuel cell with high newlineefficiency low cost and ecofriendly nature Fuel cells as devices for direct newlineconversion of the chemical energy of a fuel into electricity by electrochemical newlinereactions are one of the key enabling technologies for the transition to a newlinehydrogen based economy Of several types of fuel cells under development newlinetoday Proton Exchange Membrane Fuel Cells PEMFCs and Direct newlineMethanol Fuel Cells DMFCs have been recognized as a potential future newlinepower source for zero emission vehicles due to the advantages like high newlineenergy density low temperature operation and ease of handling newline newline
