SOFC OPERATING PRINCIPLE
SOFC Operating Principles
The basic structure of an SOFC consists of a solid electrolyte (usually a ceramic) positioned between an anode and a cathode. Fuel is delivered to the anode and oxidant, typically air, is delivered to the cathode. The electrodes are solid porous structures that allow the fuel and air to diffuse to the electrolyte and the products of the electrochemical reaction on the anode side to diffuse away from the electrolyte. The electrolyte conducts the oxygen ions formed by the electrochemical reduction of molecular oxygen from the cathode side to the anode side of the SOFC. Fuel diffuses through the anode to the anode/electrolyte interface. Here it reacts catalytically with the oxygen ions, releasing electrons that are transported through an external circuit, producing electricity. Individual cells are linked with a metallic interconnect in electrical series to increase voltage and power and can be stacked to achieve an optimal stack size. A number of stacks can be arrayed within an enclosure to form an SOFC module. Single or multiple modules may be aggregated and integrated with subsystems to deliver air and fuel, to recover heat, and to convert the generated electricity from direct current (DC) to alternating current (AC), forming an SOFC power system.
SOEC Operating Principles
The basic structure and operating principles of a SOEC are exactly the same as those of a SOFC, which are described above. However, in terms of operation, a SOEC is essentially the reverse of that of a SOFC, where instead of using hydrogen to produce electricity, a SOEC utilizes electricity to produce hydrogen.

CNC Machining Metal False Stacking Parts
CNC Machining Metal False Stacking Parts
SOFC/SOEC industry is a promising and revolutionary technology that generates electricity or produces hydrogen through the process of solid oxide fuel cells and solid oxide electrolysis cells. Its efficient energy conversion, low environmental impact, and high fuel flexibility have great potential to reshape the power generation and energy storage sectors.
In the SOFC industry, the stack is a relatively expensive part of the product module. When making a test machine, in order to ensure the reliability of other system modules first, CNC machining metal false stacking parts will be used instead of the electric stack to test whether the design of other modules is reasonable, so as to avoid damage to the electric stack due to problems with other modules. Dummy piles are generally made of high-temperature nickel-based alloy materials and machined.

Principle and composition structure
A fuel cell mainly consists of three parts, namely electrodes, electrolyte diaphragm and external circuit (current collector).
Electrode
Fuel gas and oxidizing gas are introduced from the anode and cathode of the fuel cell respectively. The electrode can be mainly divided into two parts, one is the anode (Anode) and the other is the cathode (Cathode). The thickness is generally 200-500mm; its structure is different from the flat electrode of the general battery. The electrode of the fuel cell has a porous structure. , so the main reason for designing a porous structure is that most of the fuels and oxidants used in fuel cells are gases (such as oxygen, hydrogen, etc.), and the solubility of gases in the electrolyte is not high. In order to improve the actual operating current density of the fuel cell and To reduce polarization, electrodes with porous structures were developed to increase the electrode surface area participating in the reaction. This is also one of the key reasons why fuel cells were able to move from the theoretical research stage to the practical stage. The key to the electrode performance of a fuel cell lies in the performance of the catalyst, the material of the electrode, and the manufacturing process of the electrode. At present, the electrodes of high-temperature fuel cells are mainly made of catalyst materials, such as Y2O3- of solid oxide fuel cells (SOFC). Stabilized-ZrO2 (YSZ for short) and nickel oxide electrodes of molten carbonate fuel cells (MCFC for short), etc., while low-temperature fuel cells are mainly composed of a gas diffusion layer supporting a thin layer of catalyst material, such as phosphoric acid fuel cells (referred to as phosphoric acid fuel cells) Platinum electrodes for PAFC) and proton exchange membrane fuel cells (PEMFC for short), etc.
Electrolyte separator
The main function of the electrolyte separator is to separate the oxidant and the reducing agent and conduct ions. Therefore, the thinner the electrolyte separator, the better. However, the strength must also be taken into consideration. As far as the current technology is concerned, its general thickness is about tens to hundreds of millimeters. . To prevent the mixing of the two gases from causing a short circuit within the battery, the electrolyte is usually a dense structure [3]. As for materials, there are currently two main development directions. One is to first make a porous separator from insulating materials such as asbestos (Asbestos) film, silicon carbide SiC film, lithium aluminate (LiAlO3) film, and then immerse it in molten lithium-potassium carbonate. Salt, potassium hydroxide and phosphoric acid are used to make it adhere to the membrane pores. The other is to use perfluorosulfonic acid resin (such as PEMFC) and YSZ (such as SOFC). In addition, since the electrolyte membrane used is solid, electrolyte corrosion can be avoided.
External circuit (current collector)
Also known as a Bipolar Plate, it has the functions of collecting current, separating oxidants and reducing agents, channeling reaction gases, etc. The performance of the current collector mainly depends on its material properties, flow field design and processing technology.

SOFC development direction
SOFC is widely used in power generation. Due to its high efficiency, small size and light weight, it is an ideal energy-saving power source. SOFC technology has many application directions and is of great significance. It is an efficient and clean utilization of fossil energy such as natural gas and coal, and An effective way to use hydrogen energy greenly and efficiently is also an important development direction to achieve my country's carbon peak and carbon neutrality goals. In addition, SOFC has shown broad application prospects in scenarios such as combined cooling, heating and power generation in data centers, distributed energy sources such as hospitals and hotels, ship power supplies, biogas/landfill gas power generation, and coal gasification power generation.
