Problems solved by technology

However, for small two-wheeled or three-wheeled hydrogen vehicles, especially two-wheeled bicycles, it is difficult to place gas cylinders on the body, which limits the volume of the gas cylinders. If the volume of the gas cylinders is not limited, the body is relatively large

Embodiment 1

[0016] Fig. 1 is a schematic diagram of the design fixed on the car body and installed in the rim.

[0017] The fuel and oxidant gas used in the hydrogen vehicle is realized by the ring storage bottle system in the rim, which is composed of an inflation valve, a ring gas storage bottle, a gas pressure reducing valve, connecting joints and pipelines. The annular gas storage cylinder 13 of this example is fixed on the vehicle body through the gas cylinder bracket 20, and has the anti-collision protection of the annular gas storage cylinder 13 by the rim 12 and the sheath 17 fixed on the rim 12. The inflation valve, the gas decompression valve and the gas connecting joint are all fixed on the car body and do not rotate with the wheels, and can be realized by conventional techniques.

Embodiment 2

[0019] FIG. 2 is a design schematic diagram of the ring-shaped gas cylinder 13 fixed on the rim 12 proposed by the present invention.

[0020] The annular gas storage bottle 13 is fixed on the rim 12, the inflation valve 21 is located at the center of the wheel shaft 16, and the stored gas is positioned on the wheel shaft 16 through the gas decompression valve and the connecting joint assembly 30. At this time, the gas storage bottle 13, the gas charging valve 21. The connecting sleeve 30 rotates with the wheel.

[0021] FIG. 3 is a schematic diagram of the structure of the connecting sleeve 30 . For the mode of this example, the gas decompression valve (not shown on the figure) is installed on the wheel rim 12 or on the axle 16, and rotates with the wheel, and then the gas circuit is connected to the connection sleeve 30. The casing 30 adopts a rotary sealing structure, one end of the casing 30 is connected to the gas source pipeline 19 located at the center of the wheel sha...

Abstract

The present invention relates to wheel loaded fuel and oxidant gas storing system for fuel cell vehicle. The wheel loaded fuel and oxidant gas storing system consists of an inflating valve, a ring gas storing cylinder, a gas pressure reducing valve, a connecting joint, a pipeline and other parts. This kind of gas storing system can reduce the occupation of the gas storing cylinder to the vehicle body space. When it is used in hydrogen fuel cell bicycle, it can reduce the appearance volume of the bicycle and facilitate the arrangement of the other parts.

Description

technical field [0001] The invention is mainly used for the storage and supply of the working gas of the hydrogen proton exchange membrane fuel cell, such as hydrogen and oxygen. Background technique [0002] The hydrogen proton exchange membrane fuel cell stack uses hydrogen and oxidant as the reaction substances. When the exchange membrane generates potential and forms a circuit, it can do work externally. This is the basic power principle of hydrogen proton exchange membrane fuel cell vehicles (hereinafter referred to as hydrogen vehicles). . At present, the fuel hydrogen used by most hydrogen vehicles is stored in high-pressure gas cylinders, and the oxidant is generally air. If oxygen is used as the oxidizing agent, it must also be stored on the vehicle beforehand. At present, the storage of hydrogen and oxygen used by hydrogen vehicles is mainly on the vehicle body. However, for small two-wheeled or three-wheeled hydrogen vehicles, especially two-wheeled bicycles, i...
