Title:
HYDROGEN GENERATING METHOD, HYDROGEN USE METHOD, AND ELECTRICITY GENERATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/118772
Kind Code:
A1
Abstract:
Hydrogen can be efficiently generated with a small amount of electrolysis energy. Generate hydrogen by electrolysing liquid ammonia having electrolytes added thereto, and generate electricity by reacting the generated hydrogen with oxygen. As the electrolysis energy for the liquid ammonia is low, a large amount of hydrogen can be efficiently generated. The electrical energy obtained from the hydrogen generated by electrolysis is greater than the electrical energy needed for the electrolysis of the liquid ammonia. Therefore, a small electricity source can be converted to a large electrical power and used.
