As depletion of the conventional fossil fuel is drawing near, efforts for development of alternative energy sources are being accelerated. Hydrogen is the most favorable candidate for the next generation alternative energy which is both eco-friendly and of high potential efficiency. However, hydrogen is prone to powerful detonation when exposed to air. In order to prevent this potential danger, the safety of storage containers which may be expose to hydrogen gas must be ensured by evaluating the leak-tightness in terms of diversified test methods.
Generally in hydrogen environment the mechanical properties of metallic material has tendency to deteriorate in terms of tensile strength and elongation. Although many theories exist as to what causes embrittlement phenomenon, it is imperative to establish the quantitative method for measuring the hydrogen content in the material as well as dealing with the raw data to make it resonable. In this paper, electrochemical inducing method to generate the data for hydrogen content in the specimen has been introduced. By this experiment, we found that the quantity of hydrogen content and its characteristic depend on the current density, flowing time and liquid solution. The study of measuring method for the hydrogen content using TDS(Thermal Desorption Spectroscopy) and tensile testing to figure out critical hydrogen content which is directly related to safety also has been carried out.
