Hydrogen Energy Fuel Cell Stack

Tinheo is a manufacturer specializing in customizing new energy electronic control boxes and hydrogen energy fuel cell stack casings. It provides one-stop customized solutions for CNC processing and surface treatment of new energy electronic control boxes and hydrogen energy fuel cell stack casings. With its superb technology and many years of rich customization experience, the company has won the trust and praise of many new energy battery controllers and hydrogen energy fuel cell stack R&D institutions.

The accuracy, air tightness, parallelism, roughness and relative position of the threaded holes of the hydrogen energy fuel cell stack shell will affect the performance of the stack. Dongguan Tianhong has rich experience in the processing and customization of hydrogen energy fuel cell stack shells. Practical experience, sophisticated high-precision CNC equipment and friction stir welding equipment. The company has 100 CNC machining centers over 1 meter, including horizontal CNC machining equipment (specialized in 6-sided box customization, with a maximum stroke of 1500*700*800mm), and can quickly provide customers with hydrogen energy fuel cell stack shells Custom processing.

A hydrogen energy fuel cell stack is composed of multiple fuel cell units stacked in series. The bipolar plates and the membrane electrode MEA are alternately stacked, and seals are embedded between each monomer. After being pressed by the front and rear end plates, they are tightened with screws to form a fuel cell stack. The hydrogen energy fuel cell stack is the place where electrochemical reactions occur and is the core part of the fuel cell system (or fuel cell engine).

1.The stack body. It is the core of the fuel cell stack system, where electrochemical reactions occur to provide power.
2.Fixed module of stack and shell. Ensure that the stack and the shell are firmly fixed together to avoid the stack from sliding in the shell under external load, thereby affecting the structural stability of the stack.
3.Inspection module. As the only electronic module in the fuel cell module, it is mainly used to collect the fuel cell voltage and make simple fault diagnosis (such as the lowest cell voltage alarm, etc.). This information is interacted with the fuel cell controller.
4.Bus module. This module is part of the high-voltage electrical components in the fuel cell module. Its main function is to collect current and output it to the outside world through the high-voltage connector.
5.Interaction module between the interior of the shell and the atmospheric environment. There should be an opening on the shell to communicate with the atmosphere, so as to avoid the accumulation of hydrogen leakage in the shell; but the opening must be waterproof to prevent external moisture from entering the shell, causing condensation and accumulation of water in the shell; in addition, the openings of the shell It should have the function of draining water outwards but preventing external liquid water from entering the inside of the shell. Various stack manufacturers have different solutions. Some use waterproof and breathable membranes installed on the packaging casing. Some use purging methods, opening purge ports on the packaging casing, and actively blowing air to remove the casing. Hydrogen and water inside the body.
