GAS ACCUMULATOR
The invention relates to a gas accumulator for storing pressure gases, in particular gaseous fuels such as hydrogen or similar. Said gas accumulator has a sealed holder, comprising a valve-actuated feed and withdrawal pipe for the pressure gas, and a solid filling of carbon nanostructures. The invention seeks to considerably increase the storage capacity of the gas accumulator. To this end, the particles of the carbon nanostructures are compressed to form larger, coherent conglomerates with increased apparent density in relation to the apparent density of the originally incoherent particles. This compression results, for example, from an ordering of the orientation of the carbon nanostructures, or from the formation of the conglomerates by pressure from unordered carbon nanostructures. In either case, by minimizing the space between the individual carbon nanostructures, the quantity of carbon nanostructures which can be introduced into the holder, and thus the volume of pressure gas storable therein, can be increased.
