Patent ID: 7455924

Claim:
An electrical power generator comprising: a) a water vapor generator for generating water vapor at a temperature of from about −20° C. to about 50° C.; b) a hydrogen gas generator attached to the water vapor generator, said hydrogen generator containing a substantially non-fluid substance which reacts with water vapor to generate hydrogen gas; said hydrogen generator optionally being attached to said water vapor generator via at least one conduit; and c) a fuel cell attached to the hydrogen gas generator; said fuel cell optionally being attached to said hydrogen gas generator via at least one conduit; and d) at least one manually or electrically controllable valve for regulating the passage of hydrogen gas and water vapor between the water vapor generator and the fuel cell wherein the water vapor generator and hydrogen gas generator are adapted to provide sufficient hydrogen for desired operation of the fuel cell; wherein the water vapor generator is at least partially filled with ice.
