[INTERNATIONAL ENGLISH) Research Institute of Korea Energy Technology (Seoul) (Kim Jong-nam) (Kim Jong-nam) Hydrogen Research Team Jo Hyun-suk (Doctor of Hydrogen Research Institute) found a clue to produce hydrogen stably without performance degradation (broken) on the rapid load change of renewable energy.

The researchers have found a technology that improves durability in a manner that adds a larger substance to prevent the electrode from being oxidized (corrosion) (power off) (power off  복 복 복).

The water-warmer apparatus for making water electrolyzing water has a cathode in which hydrogen is generated, an anode generated by oxygen. Put the separation membrane so that there is no short circuit between both electrodes and deliver ions. When applied to both electrodes in such a situation, hydrogen and oxygen are generated through the electrochemical reaction, respectively.

The efficacy reaction occurs on the electrode surface and the activity of the electrode is greatly affected by the hydrogen production efficiency. Alkaline Equipment The Equipment Most of the Equipment is using the electrode based on a relatively affordable transition metal such as nickel, cobalt, and iron. In recent years, there are studies on which non-metallic elements such as phosphorus, sulfur and boron are bonded to the transition metal electrode material to significantly improve hydrogen generation activity.

General Prostate Research focuses on research to improve activity and durability under constant operating conditions, and the core when making hydrogen into renewable energy is designed to enable the electrode to be ridiculous and sudden power production changes.

When the renewable energy is stopped, a reverse current phenomenon occurs at the cathode, and the electrode surface is oxidized, and the electrode surface is suddenly increased, the anode surface is oxidized with a rapidly enhanced voltage. If the load change is rapidly repeated in a short period, the electrode is damaged, and the performance of the device is deteriorated. Development of expanding electrode electrode that can be effectively responded to load change.

It was applied to the electrode in the hydrogen generation reaction electrode (cathode) and an amorphous cobalt produced by the electroplating process to determine the degradation behavior of the electrode when there is a load change in the above durable development electrode. Despite the excellent initial performance, when the power of 5 hours was blocked, the cobalt of the electrode surface is irreversible as cobalt hydroxide as a cobalt hydroxide.

The researchers have been added to a sacrificial anode law, known as the anti-cobalt, which is known as the corrosion-proof technology, which is known to the corrosion prevention technique of metal to inhibit the cobalt-in-electrode that may occur when there is a sudden power off, A high-end configuration electrode was produced.

The sacrificial anodic method is a technique for preventing corrosion by electrically connecting a sacrificial metal anode having a higher reactive amount of reactivity to a light metal.

The manganese-cobalt-in electrode has not been observed in performance even after 5 hours of power off, with high initial hydrogen generation performance.

The research scores were published in the Inside Back cover in the Materials and Chemicals’ International Journals, and the International Journal of Materials, and the International Journal of the Chemicals in Chemistry, and the International Journal of Chemicals.

Dr. Cho Hyun-seok said, The expansion of the sub-transformed supported electrode, which developed this time, is a technology that can contribute to the improvement of reliability for commercialization of renewable energy, said, It is a technique that can contribute to the improvement of reliability for commercialization of the device. · It would be a great help to strengthen the competitiveness of component technology.
