Hybrid cars now, fuel cell cars later.
We compare the energy efficiency of hybrid and fuel cell vehicles as well as conventional internal combustion engines. Our analysis indicates that fuel cell vehicles using hydrogen from fossil fuels offer no significant energy efficiency advantage over hybrid vehicles operating in an urban drive cycle. We conclude that priority should be placed on hybrid vehicles by industry and government.
متن کاملLong road ahead for hydrogen fuel cell cars.
IN THEIR REPORT “EFFECTS OF MARINE reserves on adjacent fisheries” (30 Nov., p. 1920), C. M. Roberts and co-authors present data indicating that fishery yields have increased in waters adjacent to marine reserves in St. Lucia and east Florida. In many developing island nations like St. Lucia in the Caribbean, fisheries are seriously overexploited, and little or no fisheries management exists. I...
متن کاملLow Cost, High Efficiency Reversible Fuel Cell (and Electrolyzer) Systems
A reversible solid-oxide fuel cell (SOFC)/electrolyzer system capable of storing electrical energy generated from renewable sources at projected round-trip efficiencies over 80% and providing backup power generated from propane at efficiencies over 60% (LHV) was studied. The systems perform all electrochemical functions using a single stack assembly with a unique systems design that stores both...
متن کاملClean, reusable and low cost heterogeneous catalyst for amide synthesis.
We have developed a heterogeneous silica catalyst that can effectively catalyse amide synthesis from acid and amine, without production of toxic by-products and with the advantage of being readily available, low cost, environmentally benign and reusable.
متن کاملElectrocatalytic performance of fuel cell reactions at low catalyst loading and high mass transport.
An alternative approach to the rotating disk electrode (RDE) for characterising fuel cell electrocatalysts is presented. The approach combines high mass transport with a flat, uniform, and homogeneous catalyst deposition process, well suited for studying intrinsic catalyst properties at realistic operating conditions of a polymer electrolyte fuel cell (PEFC). Uniform catalyst layers were produc...
