Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
A hydrogen storage module adapted to be employed in plurality inside a pressure containment means to store hydrogen as metallic hydride comprising (A) A fluted tube section of metal having good thermal conductivity, said section having a low length to diameter ratio, crimped closed at each end over the periphery of (B) a microporous filter disc, (C) the metal crimped over said periphery of said microporous filter disc having depressed, generally radially extending paths therein and (D) said fluted tube section being filled by said metal of said metal hydride to an extent of no greater than 78% of the volume of the tube section when the metal of the hydride is in a hydrogen-free condition.
Claim 2
Dependent Claim
116 words
A hydrogen storage module adapted to be employed in plurality inside a pressure containment means to store hydrogen as metallic hydride comprising (A) A fluted tube section of metal having good thermal conductivity, said section having a low length to diameter ratio, crimped closed at each end over the periphery of (B) a microporous filter disc, (C) the metal crimped over said periphery of said microporous filter disc having depressed, generally radially extending paths therein and (D) said fluted tube section being filled by said metal of said metal hydride to an extent of no greater than 78% of the volume of the tube section when the metal of the hydride is in a hydrogen-free condition.
Claim 3
Dependent Claim
23 words
A hydrogen storage module as in claim 1 wherein the ends of the tube section are generally circular and of a reduced diameter.
Claim 4
Dependent Claim
19 words
A hydrogen storage module as in claim 1 wherein the microporous filter disc is a disc of sintered metal.
Claim 5
Dependent Claim
22 words
A hydrogen storage module as in claim 1 wherein the length to diameter ratio is in the range of 1 to 6.
