Metal fuel cells [Zn-air fuel cells]

IEEE Spectrum, 2001
The author describes a zinc-air fuel cell system which may be used for everything from electric vehicles (EVs) to backup generators, and may also provide practical and efficient energy storage.

Hybrid combustion with metallized fuels

29th Joint Propulsion Conference and Exhibit, 1993
A chemical method of adding certain catalysts to improve the degradation process of a solid fuel is discussed. Thermogravimetric (TGA) analysis used to study the fundamental degradation behavior of a typical hybrid fuel (HTPB) shows that high surface temperatures increase the degradation rate. Fuels were tested in a laboratory-scale experimental hybrid

Advances in Metallic Nuclear Fuel

JOM, 1987
Metallic nuclear fuels have generated renewed interest for advanced liquid metal reactors (LMRs) due to their physical properties, ease of fabrication, irradiation behavior, and simple reprocessing. Irradiation performance for both steady-state and transient operations is excellent.

Metal-Free Motifs for Solar Fuel Applications

Annual Review of Physical Chemistry, 2017
Metal-free motifs, such as graphitic carbon nitride, conjugated polymers, and doped nanostructures, are emerging as a new class of Earth-abundant materials for solar fuel devices. Although these metal-free structures show great potential, detailed mechanistic understanding of their performance remains limited.

Laser dispersion and ignition of metal fuel particles

Review of Scientific Instruments, 2011
The development of a laser-shock technique for dispersing Al metal fuel particles at velocities approaching those expected in a detonating explosive is discussed. The technique is described in detail by quantifying how air drag affects the temporal variation of the velocity of the dispersed particle plume. The effect of particle size is incorporated by

Precious metals and fuel developments

Journal of Molecular Catalysis, 1986
Abstract Phosphoric acid fuel cells are rapidly approaching commercial availability, with major demonstration programmes in progress by electric and gas supply utilities in America and Japan. Without exception, these are catalysed by carbon-supported platinum catalysts.

INNOVATIVE METAL FUELS FOR SOLID ROCKET PROPULSION

International Journal of Energetic Materials and Chemical Propulsion, 2012
Two groups of innovative metal fuels are addressed in this paper. Three nanometric powders nominally ranging from 50 to 100 nm were contrasted to three micrometric activated aluminum powders, in terms of active metal content, specific surface area, scanning electron microscopy imaging, laser granulometry, and ignition properties in air.

Metal–Organic Frameworks Towards Desulfurization of Fuels

Topics in Current Chemistry, 2019
Petroleum is an essential source of energy for our daily life. However, crude oil contains various kinds of sulfur-containing compounds that will form sulfur oxides upon combustion and cause severe environmental problems. To reduce the environmental impact of petroleum energy, the desulfurization of fuels is necessary.
