HYDROGEN SUPPLY SYSTEM

摘要

A hydrogen supply system (Figure 1) comprises a first hydrogen storage material (1), which may be an AB5 type material, and a second hydrogen stora ge material (2) which may be a MgH2 type material; wherein the two hydrogen stores are separate. The first hydrogen storage material can be activated to release hydrogen at a lower temperature than can the second hydrogen storage material and at least a proportion of the hydrogen released from the first hydrogen storage material is utilised to activate the second hydrogen storag e material. Hydrogen released from the second hydrogen storage material is mad e available to a hydrogen consumption system (3). The system is particularly suited for use as a mobile hydrogen supply, for example to provide hydrogen to a fuel cell powered vehicle.
