Abstract: An improved system for generating electrical power using a fuel cell. More particularly, a system for generating hydrogen gas by reacting water vapor with a substantially non-fluid substance and transporting the generated hydrogen gas to the fuel cell which generates electrical power. Reacting water vapor with the non-fluid hydrogen generating substance rather than liquid water prevents caking of the non-fluid substance and deposition of byproducts onto the non-fluid substance that interfere with continued generation of hydrogen gas. Also, a non-electrically actuated valve for use in a hydrogen gas generating apparatus which regulates the generation of hydrogen as required by the fuel cell.

Abstract: Stabilized fuels and methods for the encapsulation of fuels are provided. More particularly, methods for the passivation or encapsulation of water reactive, hydrogen gas generating fuels. Water reactive fuels are encapsulated in a water vapor permeable, liquid water impermeable membrane, or coated with a water vapor permeable, liquid water impermeable oil substance to control the quantity of water that is permitted to reach the chemical fuel. In the event of damage, hydrogen generators incorporating the fuels of the invention are protected from explosions that might otherwise result from rapid, uncontrolled hydrogen generation.
