Description

Gasket for electrolysis device with water channel integrated structure The present invention relates to a gasket for an electrolytic device having a water channel integrated structure, and more specifically, to a gasket having a water channel slit hole formed to guide water between a bipolar plate and an MEA, wherein the gasket is formed from a synthetic resin material or an elastic synthetic resin material, thereby improving processability so as to reduce the cost and time associated with processing and reduce manufacturing costs, and improving airtightness so as to prevent leakage. Generally, electrolysis is a process that uses electrical energy to induce a non-spontaneous reaction. During electrolysis, positive ions are reduced at the negative electrode and negative ions are oxidized at the positive electrode; oxygen can be obtained through an oxidation reaction at the positive electrode, and hydrogen can be obtained through a reduction reaction at the negative electrode. Hydrogen and oxygen are obtained from water through such electrolysis, and the hydrogen obtained through electrolysis can be used for various purposes. For example, hydrogen is used in a wide range of applications as a process gas in industrial processes or as an energy storage medium, which is another form of electrical energy. Specifically, it is used as a major raw material and reducing agent in industries such as food, chemicals, metals, lighting, welding, deodorization, and sterilization. It is also used as a standard gas in gas analysis devices and can be used as a temporary storage medium for electricity obtained from renewable energy sources such as wind and solar power, which are supplied at low prices. In such an electrolyzer, water is supplied from the outside to the MEA (Membrane Electrode Assembly) by forming a water channel in the bipolar plate. In order to uniformly and effectively supply water supplied to the interior of the bipolar plate to the surface in contact with the MEA, the bipolar plate is subjected to multiple water channels through machining and mirror finishing or surface treatment to reduce friction, and to prevent corrosion, the material of the bipolar plate is titanium and is plated. However, conventional bipolar plates use titanium, so there is a problem where bending occurs due to stress during machining to form channels. Also, since they are made of titanium metal, it is difficult to maintain flatness, machining precision, and tolerances during manufacturing. Furthermore, difficulties arise, such as increased manufacturing costs due to the use of titanium, and the problem of increased unit costs persists.
