Fuel cell bus top hydrogen storage cabin

Abstract

The invention discloses a fuel cell bus top hydrogen storage cabin which is simple in structure, reasonable in design, safe to use and reliable. The fuel cell bus top hydrogen storage cabin is arranged at the front upper end of a bus and comprises a shell, a wedge structure inclined backwards and upwards is arranged on the upper portion of the shell, a plurality of air inlets are formed in the front of the shell, fan exhaust outlets and a plurality of air outlets are adjacently formed in the upper end of the wedge structure of the shell, fans are arranged in the fan exhaust outlets and provided with power supplies in a matched manner, and hydrogen concentration sensors are arranged at the inner top end of the shell and electrically connected with the power supplies. The fuel cell bus top hydrogen storage cabin is applicable to the technical field of bus hydrogen storage cabin design.

Description

technical field [0001] The invention relates to a hydrogen storage cabin mounted on the roof of a fuel cell passenger car. Background technique [0002] The fuel cell bus mainly uses the electric energy generated by the fuel cell as the power to drive the vehicle. Fuel cells mainly react with hydrogen and oxygen, and the product is only water, which has no pollution to the environment and has broad development prospects. However, hydrogen as the main reactant has strong leakage, flammability, and explosiveness, which makes fuel cell buses have certain safety hazards in the process of use. As an important place for arranging hydrogen storage bottles, the safety of the hydrogen storage cabin is very important; in the process of use, a small amount of hydrogen leakage will occur. If the leaked hydrogen is not discharged in time, the leaked hydrogen will continue to accumulate. Potential safety hazards arise. In order to ensure the safety of hydrogen use, existing fuel cell bu...

Problems solved by technology

However, hydrogen as the main reactant has strong leakage, flammability, and explosiveness, which makes fuel cell buses have certain safety hazards in the process of use.

As an important place for arranging hydrogen storage bottles, the safety of the hydrogen storage cabin is very important; in the process of use, a small amount of hydrogen leakage will occur. If the leaked hydrogen is not discharged in time, the leaked hydrogen will continue to accumulate. Potential safety hazards arise. In order to ensure the safety of hydrogen use, existing fuel cell buses are usually equipped with hydrogen concentration sensors at locations where hydrogen is likely to leak and accumulate. When hydrogen leakage is detected, the supply of hydrogen is cut off, allowing hydrogen to diffuse by natural diffusion. To the outside of the car, this method still has certain deficiencies, and there is a large room for improvement, such as the leaked hydrogen remaining in the hydrogen storage tank and causing complete hidden dangers.
