Titanium Bipolar Electrolyser Plate for Fuel Cell

Titanium bipolar electrolyser plate in electrolysis is a special electrode for electrolysis, usually made of pure titanium. In electrochemical processes, electrodes are usually divided into anodes and cathodes, each responsible for the flow of electrons and the flow of ions. A bipolar plate is an electrode that has both anodic and cathodic properties.

In electrolysis, titanium bipolar electrolyser plates are usually used in the fields of electroplating, electrolytic preparation and water treatment. They can withstand high voltage and high current density, but also have good corrosion resistance, which allows them to be used in harsh environments such as strong acid, strong alkali, high temperature and high pressure.

Parameters

Application: Fuel cell

Features

1. Good electrical conductivity: Titanium bipolar plates have excellent electrical conductivity and can withstand high voltage and high current density, thus effectively promoting electrochemical reactions.

2. Good corrosion resistance: Titanium bipolar plates have good corrosion resistance and can be used in harsh environments such as strong acid, strong alkali, high temperature and high pressure, and are not easily corroded and worn.

3. Good mechanical properties: Titanium bipolar plates have high strength and rigidity, can withstand large forces and pressures, and are not easily deformed and broken.

4. Lightweight: Titanium bipolar plates have a lower density and are a lightweight material that can reduce the weight of the entire electrolytic cell and improve overall efficiency.

Methods of coatings for Ti bipolar plates

A number of methods are used to deposit coatings onto metallic bipolar plates. Processes include physical vapor deposition techniques such as electron beam evaporation, sputtering and glow discharge decomposition, chemical vapor deposition techniques, and liquid phase chemical techniques such as electroplating and electroless deposition, chemical anodizing/oxidation coatings and painting.

Processing

Titanium bipolar plates can be manufactured by CNC machining, hydraulic forming and stamping, and photochemical etching. The following is a brief description and comparison of these three methods:

CNC machining: CNC machining is a method of machining using computer-controlled cutting tools. When manufacturing titanium bipolar plates, CNC machine tools can be used to perform operations such as cutting and milling of titanium plates to produce the desired shape and size.

Hydroforming and stamping: Hydroforming and stamping are methods of shaping titanium plates using hydraulic pressure and dies. When manufacturing titanium bipolar plates, hydraulic presses or punching machines can be used to punch, form, and bend titanium plates.

Photochemical Etching: Photochemical etching is a method that uses light and chemical reactions to etch the surface of a material. When manufacturing titanium bipolar plates, photoresist technology can be used to cover the parts that need to be protected, and then irradiated and etched to produce the desired shape and size.
