| Abstract: |
| The paper aims to research the relationships among microorganism, hydrogen permeation and cathodic protection. Methods for the determination of the growth and metabolism of microorganisms and the research methods for hydrogen penetration tests were given. Methods for the determination of the population growth curve, bacterial count and metabolism were introduced separately. Devanathan-Stachurski double cell technology was adopted for the hydrogen permeation test. Samples were often treated with single-sided nickel or palladium plating. A cathodic protection was applied to the cathode cell. After the hydrogen produced on the surface of the sample permeated to the side of the anode cell, a potentiostat was used to record the oxidation current of hydrogen on the surface of the sample, that is, the hydrogen permeation current. |
