NUMERICAL MODELING METHOD FOR METAL HYDRIDE TANK INTERPRETATION

摘要

PURPOSE: A calculation method of a numerical model for metallic hydride tank interpretation is provided to calculate temperature change and reaction speed corresponding to reaction with hydrogen by only calculation of the numerical model for various forms of metallic hydride tank systems for hydrogen storage. CONSTITUTION: A metallic hydride tank system is filled with a metal hydride(MH) alloy and is maintained at predetermined temperature(S110). Temperature change corresponding to heat of reaction between the MH alloy and hydrogen, reaction speed, and hydrogen concentration in the MH alloy are measured by supplying, emitting, and changing hydrogen content of the MH alloy(S120). A numerical model for the temperature change, the reaction speed, and the hydrogen concentration in the MH alloy are calculated based on the measured data(S130). The MH alloy includes a Ti-Cr-V-Fe alloy.
