Abstract:
1. A reservoir for storing hydrogen, comprising: a housing; a molded body comprising a compressed hydrogen storage material powder accommodated in the housing, the molded body causes exothermic reaction when absorbing hydrogen and causes endothermic reaction when releasing hydrogen, and the molded body has a first side and a second side opposite to the first side, wherein the molded body has a plate-like shape, the first and second sides of the molded body are flat, and the thickness of the molded body is equal to or smaller than ten millimeters; a heat medium passage formed in the interior of the housing to face the first side of the molded body, wherein the heat medium passage is flat, wherein heat is transmitted from the molded body to a heat medium in the heat medium passage when the molded body absorbs hydrogen, and heat is transmitted from the heat medium in the heat medium passage to the molded body when the molded body releases hydrogen, and wherein the heat medium passage includes a duct that has a plurality of holes that extend parallel with each other in a longitudinal direction of the duct, wherein the duct is flat, and the duct contacts the first side of the molded body; and a filter which forms a hydrogen passage, wherein the hydrogen passage is formed in the interior of the housing to face the second side of the molded body, wherein the hydrogen passage is flat, wherein the molded body includes a chamfer, wherein a main passage is formed between the chamfer and a wall of the housing and is connected to the hydrogen passage, and wherein the hydrogen is supplied from the exterior of the housing to the hydrogen passage through the main passage and is discharged from the hydrogen passage to the exterior of the housing through the main passage.
