Hydrogen Storage

Simple SummaryContent extracted from patent full text and abstract with AI.

The patent describes a novel hydrogen storage medium and method that utilize an ammonia-boron complex dissolved in a dehydrogenatable ionic liquid, with the addition of a metal-based catalyst. This system enables efficient storage and controlled release of hydrogen at relatively low temperatures and pressures, suitable for mobile fuel cells and portable electronic devices. The storage medium is regeneratable, allowing for repeated use.

Patent Abstract

The regeneratable hydrogen storage medium useful in mobile fuel cells, which is useful in hydrogen cars or portable consumers e.g. laptops, comprises an ammonia-boron complex present in a dehydrogenatable ionic liquid, and a metal-containing catalyst. The proportion of ammonia-boron complex to the ionic liquid is 0.5-20. The pressure of the storage medium is 0.7-2 bar. The catalyst quantity related to the ammonia-boron complex is 0.5-2.5. The catalyst (1-5 wt.%) is fixed on a carrier. An independent claim is included for a method of storing hydrogen.
