<P>PROBLEM TO BE SOLVED: To inexpensively provide a hydrogen barrier sheet, which is usable as packaging or pasting sheet as it is for wrapping hydrogen components such as battery cells and a case, and is not broken by vibration during transportating, moving or using, and keeps hydrogen from leaking out of place even if there is a change of thermal environment, a vibration environment, or an aging deterioration. <P>SOLUTION: A hydrogen barrier sheet comprises a sheet body formed by laminating and solidifying, or permeating and solidifying a solution of konjak powder containing 50 wt.% or more of mannan component on a sheet-like base material 11 or inside of the base material 11, and has the overall hydrogen permeability of the sheet body of 20 cm<SP POS="POST">3</SP>/m<SP POS="POST">2</SP>atm 24h or less. The base material 11 preferably comprises a nonwoven fabric made of glass fiber or carbon fiber, where a mannan permeated layer 21 permeates to form a mannan permeated layer 21. <P>COPYRIGHT: (C)2012,JPO&INPIT |
