    摘要: The present relates to a Metal hydride compressor control method for generating a variable output pressure P_desired_outPut, comprising a first step of inflowing gaseous hydrogen into a metal hydride compartment at a constant temperature and then stopping the gaseous hydrogen inflow, a second step of heating the metal hydride to a predetermined temperature which corresponds to a temperature which passes through the α+β phase at the desired output pressure P_desired_output, a third step of opening the output connection of the compressor and keeping it at a constant pressure by regulating the temperature to keep a constant output pressure P_desired_outPut until the system completely leaves the α+β phase.

    摘要: An electrochemical power system is provided that generates an electromotive force (EMF) from the catalytic reaction of hydrogen to lower energy (hydrino) states providing direct conversion of the energy released from the hydrino reaction into electricity, the system comprising at least two components chosen from: H2O catalyst or a source of H2O catalyst; atomic hydrogen or a source of atomic hydrogen; reactants to form the H2O catalyst or source of H2O catalyst and atomic hydrogen or source of atomic hydrogen; and one or more reactants to initiate the catalysis of atomic hydrogen. The electrochemical power system for forming hydrinos and electricity can further comprise a cathode, an anode, reactants that constitute hydrino reactants during cell operation with separate electron flow and ion mass transport, a source of oxygen, and a source of hydrogen. Due to oxidation-reduction electrode reactions, the hydrino-producing reaction mixture is constituted with the migration of electrons through an external circuit and ion mass transport through a separate path such as the electrolyte to complete an electrical circuit. In an embodiment, the anode is regenerated by intermittent charging with the electrodeposition of the anode metal ion from the electrolyte to the anode wherein an anion exchange with the anode metal oxide provides a thermodynamically favorable cycle to facilitate the electrodeposition.
    A solid fuel power source that provides at least one of thermal and electrical power such as direct electricity or thermal to electricity is further provided that powers a power system comprising (i) at least one reaction cell for the catalysis of atomic hydrogen to form hydrinos, (ii) a chemical fuel mixture comprising at least two components chosen from: a source of H2O catalyst or H2O catalyst; a source of atomic hydrogen or atomic hydrogen; reactants to form the source of H2O catalyst or H2O catalyst and a source of atomic hydrogen or atomic hydrogen; one or more reactants to initiate the catalysis of atomic hydrogen; and a material to cause the solid fuel to be highly conductive, (iii) at least one set of electrodes that confine the fuel and an electrical power source that provides a short burst of low-voltage, high-current electrical energy to initiate rapid kinetics of the hydrino reaction and an energy gain due to forming hydrinos, (iv) a product recovery systems such as a condenser, (v) a reloading system, (vi) at least one of hydration, thermal, chemical, and electrochemical systems to regenerate the fuel from the reaction products, (vii) a heat sink that accepts the heat from the power-producing reactions, (viii) a power conversion system that may comprise a direct plasma to electric converter such as a plasma dynamic converter, magnetohydrodynamic converter, electromagnetic direct (crossed field or drift) converter, {right arrow over (E)}×{right arrow over (B)} direct converter, and charge drift converter or a thermal to electric power converter such as a Rankine or Brayton-type power plant.
