Custom Fuel Cell Bipolar Plate of Photo Etching Technology

The fuel cell bipolar plate is mainly used for the internal devices of the fuel cell. A fuel cell is a chemical device that directly converts the chemical energy of the fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power generation and nuclear power generation. Because the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so it has high efficiency; in addition, the fuel cell uses fuel and oxygen as raw materials, and at the same time There are no mechanical transmission parts, so it emits very little harmful gas and has a long service life. This shows that from the perspective of energy conservation and ecological environment protection, fuel cells are the most promising power generation technology.

A fuel cell is usually composed of an electrolyte plate forming an ion conductor, a fuel electrode (anode) and an air electrode (cathode) arranged on both sides, and gas flow paths on both sides. The function of the gas flow path is to make the fuel gas and air (oxidant) Gas) can pass in the flow path. Among them, the fuel bipolar plate plays a vital role. TMN has produced many different types of fuel bipolar plates with different designs. The main material is stainless steel 316L, titanium material with thickness from 0.15mm to 2.0mm, etching through and half etching are all available.

The advantages of bipolar plate fuel cell

A fuel cell is a device that directly converts the chemical energy of fuel into electrical energy. Theoretically speaking, as long as the fuel cell is continuously supplied with fuel, the fuel cell can generate electricity continuously. It has been hailed as the fourth-generation power generation technology after water power, thermal power, and nuclear power.

High power generation efficiency

Low environmental pollution

Higher energy

Less radiation

TMN has produced fuel cell bipolar plates with stainless steel 316L & Titanium material with thickness from 0.1mm to 2.0mm ,etching through and half etching for channels are all available .
