the present paper explores the impact of an on-board hydrogen harvesting system (fuel reformer) on the overall efficiency of a fuel-cell powered vehicle. various methods of hydrogen production for automotive applications have been discussed first. as the hydrogen production is one of the major challenges for application of proton exchange membrane (pem) fuel cells, especially in vehicular indus...
the hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of h+ to nabh4. the sulfonated porous carbon (spc) is used as a source of hydrogen ion and catalyst. it is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of nabh4 to generate hydrogen gas at room temperature in comparison to amberlyst-15 and nafion-nr50. the ki...
abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
this is a report on the study of high melt flow, highly isotactic polypropylene homopolymer synthesized in liquid monomer using a fifth generation ziegler-natta catalytic system. at highest catalyst productivity, the response of thecatalyst to hydrogen as chain transfer is studied. melt flow rate is controlled by hydrogen as chain transfer from 0.4 to 300 g/10min with changing the amount of hyd...
Glucose is a 6-carbon carbohydrate compound present in plants and the ingredient for hemicellulose which makes up 30% of plants’ total mass. The current study uses glucose as reactant and evaluates hydrogen generation at different temperatures and different amounts of input flow of glucose – water mixture. Hydrothermal gasification method is used for hydrogen generation in an open system with c...

The reaction between fine aluminum particles and water over the past fifty years, due to high energy generation and green products is in consideration. But all aluminum particles have an inactive oxidative layer and in case of Nano-Al this layer has high ratio of particles. So, efficiency of hydrogen produced by the reaction between water and aluminum is less than the theoretical value. There a...
Extensive research has been carried on the molecular adsorption in high surface area materials such as carbonaceous and MOFs well atomic bonded hydrogen metals alloys. Clathrates stand among ones to be recently suggested for storage. Although, simulations predict lower capacity than expected by DOE norms, additional benefits of clathrates low production operational cost, fully reversible reacti...
