Abstract:
1. A hydrogen storage tank comprising: an outer cylinder; and at least one cylindrical hydrogen storage module positioned within the outer cylinder, the at least one cylindrical hydrogen storage module having an outer diameter smaller than an inner diameter of the outer cylinder wherein a hydrogen passage is formed between an inner peripheral surface of the outer cylinder and the at least one cylindrical hydrogen storage module, each cylindrical hydrogen storage module comprising: wherein the sub passages comprise a plurality of guide members that circulate the heating fluid and cooling fluid throughout the sub passages, wherein the heating fluid comprises hydrogen for burning and oxygen and each of the heating/cooling elements include a catalyst that facilitates a burning reaction of the hydrogen burned with the oxygen, wherein the at least one main passage comprises a first main passage that permits the hydrogen for burning to flow therethrough and a second main passage that permits the oxygen to flow therethrough, wherein the sub passages include a first sub passage situated on one of opposite sides of a porous carrier that holds the catalyst and communicates with the first main passage and a second sub passage situated on the other side of the porous carrier and communicates with the second main passage, wherein each cylindrical hydrogen storage module has a discharge passage that communicates with the second sub passage.
