Embodiment Construction

[0030] see figure 1 , is a schematic diagram of the hydrogen forced exhaust system involved in the present invention. The invention is used to exhaust the hydrogen leakage of the hydrogen supply system of the fuel cell car. The hydrogen exhaust system includes a hydrogen sensor and a collector arranged at the hydrogen accumulation point in the car. The collector is connected to the fan through a closed pipeline. The hydrogen sensor measures the hydrogen concentration at the hydrogen accumulation point. When the hydrogen concentration exceeds the specified value, the fan is turned on, and the hydrogen is discharged from the collector through the fan through the exhaust pipe.

[0031] Depend on figure 1 It can be seen that multiple hydrogen gathering points can be set up according to the actual needs in the car, and each hydrogen gathering point is equipped with a separate hydrogen forced exhaust system, that is, each hydrogen gathering point is equipped with a collector, a hyd...

Abstract

The invention discloses a hydrogen strong exhaust system and a hydrogen strong exhaust method. The hydrogen strong exhaust system comprises a hydrogen sensor arranged at a hydrogen accumulating point inside an automobile and a collector, wherein the collector is connected with a fan through a sealed pipeline, and the hydrogen sensor is used for measuring hydrogen concentration of the hydrogen accumulating point. When the hydrogen concentration exceeds a specified value, the fan is switched on, and the hydrogen passes through the fan from the collector, and is exhausted through an exhaust pipe. Due to the fact that a fuel battery automobile hydrogen strong exhaust system is added, hydrogen at the hydrogen accumulating point is exhausted in a forced mode, the exhausting mode is changed from a passive mode to an active mode, accumulation concentration of the hydrogen is reduced, and safety of usage of hydrogen is effectively ensured.

Description

technical field [0001] The invention belongs to the field of fuel cell cars, and in particular relates to a hydrogen forced exhaust system and a hydrogen forced exhaust method for a hydrogen supply system of a fuel cell car. Background technique [0002] Fuel cell cars use the electric energy generated by the reaction of hydrogen and oxygen as power, which has the characteristics of cleanliness and environmental protection. During the operation of a fuel cell car, the hydrogen supply system has uncertain hydrogen leakage or micro-leakage due to various reasons such as vibration, and it is easy to accumulate at relatively high points on the bottom of the vehicle and inside the vehicle. This kind of hydrogen continues to accumulate. When using hydrogen, there is a certain safety risk in using hydrogen. In order to ensure the safety of hydrogen use, the existing method adopts the method of installing hydrogen sensors at the accumulation points where hydrogen is easy to accumul...
