Abstract

An embodiment of the present invention is a portable hydrogen generation system for operating a vehicle powered by either the hydrogen internal combustion engine or a fuel cell using active metals such as sodium potassium, magnesium, aluminum or iron in the form of an emulsion, and a method thereof. The emulsion comprises a metal powder pre-mixed with oil. In the case of sodium, potassium and magnesium, the metal is reacting with water at or near room temperature. However, in the case of aluminum and iron, the metal is reacting with alkali hydroxide solutions. The system is controlled and managed by a microprocessor in order to generate hydrogen on demand at or near room temperature with a very high efficiency.
