High-performance hydrogen fuel cell using nitrate reduction reaction on a non-precious catalyst.
The H(2)-NO(3)(-) electrochemical cell using nitrate reduction on a non-precious cathode catalyst shows much improved efficiency despite ∼75% reduction of Pt metal loading as compared to typical PEMFCs using typical ORR on precious catalysts.
متن کاملElectrocatalysis for the Hydrogen Economy
This chapter deals with the concept of “hydrogen economy”, which was introduced by John O.M’ Bockris in 1972. We summarize the fundamental principles and the progress for the reactions relevant to the hydrogen economy, namely the hydrogen and oxygen evolution for water electrolyzers, and the hydrogen oxidation and oxygen reduction for fuel cells. The activity of each reaction can be correlated ...
متن کاملHigh performance platinized titanium nitride catalyst for methanol oxidation.
Platinized TiN is shown to be a very good catalyst for the electrochemical oxidation of methanol; it does not contain Ru and the CO poisoning effect is alleviated by the presence of TiN.
متن کاملHydrogen Economy - An Opportunity for Chemical Engineers?
Fossil fuels have provided a convenient and plentiful energy source, and have been used profitably in all sectors of the global economy. However, continued reliance on fossil resources must take note of, and may even be placed in jeopardy by several factors. First, worldwide oil demand continues to increase, and replacing the produced oil is technically and politically demanding and very capita...
متن کاملEngineering Challenges of the Hydrogen Economy
HE TERM “HYDROGEN ECONOMY” is the title of a recent book [Rifkin, 2002], but the concept of using hydrogen as fuel for transportation systems has been advocated by environmentalists and others for at least three decades. There is no universally accepted definition of the “hydrogen economy,” but it is generally viewed as the replacement of the vast majority of petroleum fuels used by transportat...
