The low volumetric energy density of hydrogen poses challenges when designing an aircraft, where weight and volume are critical.[5] To reduce the size of the tanks liquid hydrogen may be used, requiring cryogenic fuel tanks.[5][6] Cylindrical tanks minimise surface for minimal thermal insulation...

At 700bar, hydrogen has around 1/6th the volumetric energy density of jet fuel, meaning if the same tank space is available, it will only have around 1/6ththe range, maybe slightly more using a fuel cell. The best option for volumetric energy density is liquification. As a liq...

Fuel storage is another crucial issue in the fuel cell application. It is restricted by several factors, such as the volumetric and gravimetric energy density, the weight and lifetime of the fuel container, the conversion efficiency of the chemical energy to electricity, the safety of the fuel,...
Using density functional theory to study the activity of the first O–H in water activated by Ga–In and Ga–Sn clusters, and using displacement energy to explore the solubility of aluminum in Ga–In and Ga–Sn, the experimental phenomena of reaction rate and crack size were theoretically exp...
