<P>PROBLEM TO BE SOLVED: To enable accurate determination of the strength and a damage state of a tank. <P>SOLUTION: A high pressure tank 1 for a fuel cell includes: a means 7 for detecting impedance for a capacitance amount of electrodes 5 and 6 and a tank structure, the electrodes being located on both ends of the tank; and a monitoring means 8 for determining the strength and the damage state of the tank 1 on the basis of impedance information. According to the high pressure tank 1 for the fuel cell, an impedance increase for a capacitance amount caused by an increased distance between CFRPs (carbon fiber reinforced plastic) 3 is detected, and thereby an increase of the depletion, such as the boundary separation and a crack in the tank structure, is sensed to perform supervisory control. <P>COPYRIGHT: (C)2012,JPO&INPIT |
