Method for evaluating hydrogen generation reaction

A hydrogen generation reaction assay method, comprising:

• charging hydrogen into a steel material to be evaluated until a hydrogen storage capacity is saturated;
• immersing the steel material with a saturated amount of hydrogen storage, a reference electrode, and a counter electrode in an electrolyte solution containing an additive that promotes hydrogen intrusion into the steel material, and then measuring a change in a current flowing between the steel material and the counter electrode when sweeping a voltage between the steel material and the reference electrode, the steel material serving as a working electrode;
• and
• evaluating a hydrogen generation reaction on a surface of the steel material based on the measured change in the current.

A method for evaluating a hydrogen generation reaction on a steel material, comprising:

• preparing a steel material saturated with hydrogen;
• immersing the hydrogen-saturated steel material in an electrolyte solution containing an additive that promotes hydrogen intrusion;
• applying a voltage sweep between the steel material and a reference electrode while measuring a current between the steel material and a counter electrode;
• and
• determining reaction rate coefficients for hydrogen generation reactions based on the measured current.
