Problems solved by technology

[0005] However, when making a model that reflects various material properties such as equilibrium pressure and activation energy, there are large errors from the experiment due to the complexity of the calculation formula and the complexity of the necessary variables, which may reduce the reliability or cause a large amount of calculation. , but there are problems in the efficiency and practicality of the analysis
[0006] In addition, there is a problem that motion analysis at the microscopic scale is only limited at the system scale at which analysis can be performed.

Abstract

A method of analyzing a numeric model for a metal hydride tank, which calculates the temperature change and the change of a reaction rate and the hydrogen concentration in the alloy resulting from a hydrogen reaction based on various user conditions with respect to metal hydride (MH) alloy tanks having various shapes when MH alloy tanks are actually used. The method includes (a) inputting a temperature (T), a real reaction flow rate (QR), and an initial data value of hydrogen concentration (C) for each cell of a model, (b) calculating a possible reaction rate (RP) depending on the temperature (T) and the hydrogen concentration (C) in the metal hydride alloy with respect to each cell, (c) calculating a possible flow rate (QP) with respect to an entire MH alloy region, and (d) calculating a k between the real reaction flow rate (QR) and the possible reaction flow rate (QP).

Description

technical field [0001] The present invention relates to an analysis method of a composite numerical model for a metal hydride alloy tank and a method for obtaining a metal hydride alloy tank, and more specifically relates to a method of introducing a reaction rate that can be generated in a metal hydride alloy and controlled by a user The ratio of the limited actual reaction rate, that is, the concept of the rate factor (rate factor) k variable, can be calculated to reflect the actual use of various shapes of metal hydride (MH, metal hydride) alloy tanks. Analytical method for composite numerical model for metal hydride alloy tanks of temperature change, reaction rate, and hydrogen concentration change in the alloy due to hydrogen reaction in personnel conditions. Background technique [0002] Hydrogen is rich in resources, easy to convert into other forms of energy, and has excellent advantages as an energy storage medium. Therefore, it is expected to become a powerful futu...
