  • Hydrogen fuel storage and delivery system
    Patent number: 4328768

The microspheres are directed from the storage chamber to a heated chamber where the hydrogen gas is diffused through the outer surface of the microspheres and delivered to an engine for use as a fuel. After substantially all the hydrogen gas is removed, the microspheres are transported to another storage chamber from which they are completely removed for refilling with hydrogen gas while the first mentioned storage chamber is refilled with fueled microspheres.
