Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
107 words
An interstitial hydrogen fuel system, comprising: a metal for interstitially storing hydrogen as a metal hydride; a plurality of gas tight containers containing said metal hydride; a hydrogen manifold; a valve means for each of said gas tight containers operatively connected for coupling said gas tight containers to said hydrogen manifold, pressure transducers operatively connected for sensing the gas pressures in said containers, and control means connected to said valve means said control means including logic means for producing a control signal for opening each of said valves in a mutually exclusive manner as a function of pressure in said containers as sensed by said pressure transducers.
Claim 2
Dependent Claim
107 words
An interstitial hydrogen fuel system, comprising: a metal for interstitially storing hydrogen as a metal hydride; a plurality of gas tight containers containing said metal hydride; a hydrogen manifold; a valve means for each of said gas tight containers operatively connected for coupling said gas tight containers to said hydrogen manifold, pressure transducers operatively connected for sensing the gas pressures in said containers, and control means connected to said valve means said control means including logic means for producing a control signal for opening each of said valves in a mutually exclusive manner as a function of pressure in said containers as sensed by said pressure transducers.
Claim 3
Dependent Claim
