Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an evaluation device for a hydrogen supply system using a highly reliable MH alloy. SOLUTION: The evaluation device comprises a time step setting part 27 for dividing an operation time for a container filled with a hydrogen storage alloy into small time intervals for analysis, a heat analysis part 23 for performing heat conduction analysis in each time step divided by the time step setting part assuming zero hydrogen migration and calculating parameters regarding the temperatures of inner portions of the MH container, a hydrogen relative parameter calculation part 24 for calculating parameters regarding hydrogen migration in each time step identical with that of the heat conduction analysis by a heat conduction analysis means assuming the zero hydrogen migration and calculating hydrogen reaction heat, a temperature parameter correction part 25 for correcting the parameters regarding the temperatures using the reaction heat, and a hydrogen parameter correction part 26 for correcting the parameters regarding the hydrogen migration using the parameters regarding the corrected temperatures.
