Problems solved by technology
Although this method avoids the use of external high-voltage power supply and increases the net efficiency of the system, it also needs to fill the air storage tank with air after the air system is started for the next start-up, which increases the failure of the system point, reducing the reliability and stability of the system

Embodiment Construction
[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0017] An embodiment of a fuel cell of the present invention
[0018] The fuel cell includes a control system, a heat dissipation system, a hydrogen delivery system, and an air oxygen supply system. The gas storage tank in the power system, the gas storage tank in the vehicle air brake system is used as the gas source of the fuel cell, when the fuel cell starts, the gas supply pipeline is opened, and the gas stored in the vehicle air brake system The tank delivers compressed air to the fuel cell through the gas supply pipeline as a raw material for the reaction gas of the fuel cell.
[0019] Because the gas in the air storage tank in the vehicle air brake braking system is high-pressure air of 0.7 MPa, and what the fuel cell needs is low-pressure air, for this reason, the present invention is also between the air storage tank and the fuel c...

The invention relates to a fuel cell and a vehicle employing the same, and belongs to the technical field of fuel cells. An air storage tank in an air brake braking system of the vehicle is adopted as an air source of the fuel cell; when the fuel cell is started, the air storage tank in the air brake braking system of the vehicle transmits compressed air to the fuel cell through a supply air pipe, and provides the compressed air to a cathode of the fuel cell; and chemical energy in hydrogen in the fuel cell and oxygen in the compressed air is converted into electric energy to achieve external power generation through electrochemical reaction, so that startup of the fuel cell is achieved. An air compressor or a fan does not need to be individually configured for a fuel cell system for startup; and an emergency air supply does not need to be added for startup, so that the cost of the system is reduced; and the reliability and the stability of the system are improved.
Description
technical field [0001] The invention relates to a fuel cell and a vehicle using the fuel cell, belonging to the technical field of fuel cells. Background technique [0002] The reliability, stability and system efficiency of the fuel cell starting device and method directly affect its safety and the cost of the entire life cycle. Existing proton exchange membrane fuel cells use fuel hydrogen and compressed air as reaction gas raw materials, and the hydrogen and oxygen in the air inside the cell convert the chemical energy in the gas into electrical energy through an electrochemical reaction to achieve external power generation. Existing fuel cell devices include structures such as control systems, heat dissipation systems, hydrogen delivery systems, and air oxygen supply systems. In order to supply hydrogen and air to fuel cell stacks smoothly, high-voltage components (such as engines, air compressors, blowers, etc.) are generally used. , pumps, etc.), and for the start of ...
