耐圧容器が非常に大きくなる傾向があった。However, although breathable insulation materials such as rock wool glass wool and ceramic fiber have high insulation performance in the air (about 0.03Kcal/hr1.c), their insulation performance is poor in a hydrogen gas atmosphere. There was a drawback that it decreased sharply (about 0.15 Kcal/hr-s+·"c). In addition, in order to achieve the target thermal insulation properties, the thickness of the insulation material inserted into the inner wall of the pressure vessel must be increased, and as a result, the pressure vessel that constitutes the metal hydride filled container tends to become very large. there were.
