Patent number: 7954519Abstract: Safe storage of volatile compounds or elements is provided by utilizing storage configurations that take advantage of the diffusibility and release characteristics of cell-based materials, such as foam materials. Such configurations may provide storage of hazardous, liquefied gases in closed-cell foam material. Release of gas/liquid from the foam is restricted by the need for the gas to diffuse through the closed cells. Because rapid release is prevented, storage safety is greatly improved.Type: GrantFiled: February 18, 2005Date of Patent: June 7, 2011Assignee: Intelligent Energy, Inc.Inventors: Michael R.
