Description

Power vertically oriented monopolar water electrolysis stack

A power vertically aligned monopolar water electrolysis stack is disclosed. More specifically, a power vertical alignment type monopolar water electrolysis stack with a novel structure is disclosed.

Most of the hydrogen used to realize the modern hydrogen society is gray hydrogen, which is extracted by reforming natural gas and by-product hydrogen that comes out as a by-product of petrochemical processes.

However, gray hydrogen is far from reducing carbon compounds to solve recent environmental problems. As a method that does not emit carbon dioxide or pollutants purely, the method of obtaining hydrogen using water electrolysis is the most widely known method. . To this end, various water electrolysis methods are being developed according to the operating environment and technology.

Water electrolysis aims to obtain hydrogen and oxygen by injecting water and electricity, and the output produced at this time is hydrogen and oxygen, among which hydrogen is high-purity (99%↑) hydrogen. Therefore, water electrolysis can be said to be the optimal method to meet the reduction of carbon compound generation required by the current hydrogen economy.

PEM (polymer electrolyte membrane) type water electrolysis has many parts to consider, such as the components constituting PEM, operating temperature, voltage, and purity of water as a reaction raw material. Since it is on the side, various technologies such as technology to properly maintain it, technology to properly arrange components to derive optimal efficiency, and electric control and water supply to continuously maintain maximum efficiency during electrolysis are required.

In the case of water electrolysis using PEM, which is currently being researched and applied a lot, a method of deriving maximum efficiency is used by connecting large area unit cells in series. However, even if the performance of the stack is deteriorated due to this, it is difficult to know where the problem occurred, and in order to maximize stack efficiency and prevent gas leakage, a structure that takes a significant load is devised and applied.

In the case of PEM, if the temperature exceeds 120℃, the main parts become overworked and the operation becomes impossible.

In addition, the bipolar type water electrolysis stack, which is a conventional series connection method, has the advantage of obtaining maximum performance in that unit cells are connected in series, but if the target performance does not come out depending on the stacking structure, which unit There is a disadvantage in that it is not easy to find out whether a problem has occurred in the cell, and it is not easy to process accordingly.
