Fuel cell car

Abstract

The invention discloses a fuel cell car. The fuel cell car comprises a methyl alcohol hydrogen producer, a fuel cell and a car motor, wherein the methyl alcohol hydrogen producer comprises a methyl alcohol storage container, a raw material conveyor, a reformer and a hydrogen purifier; the reformer comprises a heat exchanger, a gasifying chamber, a reforming chamber and a separating chamber, and the hydrogen purifier is arranged in the separating chamber; the lower and middle parts of the reforming chamber are at the temperatures of 300-420 DEG C, and the upper part of the reforming chamber is at the temperature of 400-570 DEG C; the temperature in the separating chamber is set into 350-570 DEG C, hydrogen is obtained at the hydrogen producing end of the hydrogen purifier in the separating chamber, and the hydrogen is supplied to the fuel cell after heat exchange is carried out in the heat exchanger; the fuel cell comprises at least two fuel cell groups, and is used for producing electricity through the electrochemical reaction of the hydrogen and oxygen and supplying the car motor with electricity; the car motor is used for driving a car shaft to rotate and accordingly driving the car to run. The methyl alcohol raw material can be converted to the hydrogen at a high speed, the methanol conversion efficiency and utilizing rate are high, and the purification of hydrogen containing gas is easy.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a fuel cell vehicle. Background technique [0002] At present, the vast majority of automobiles use gasoline and diesel as fuel, which not only consumes a large amount of oil resources, but also causes serious air pollution due to automobile exhaust. In response to this resource problem and environmental problem, the development of electric vehicles has become very important. An electric vehicle refers to a vehicle powered by an on-board power supply and driven by a motor to drive the wheels. Electric vehicles include pure electric vehicles, hybrid vehicles and fuel cell vehicles. In the prior art, a fuel cell vehicle refers to an electric vehicle equipped with a fuel cell as a power source for driving power. In the process of power generation, fuel cells need hydrogen as an electrochemical reaction material. In the prior art, the hydrogen used by the fuel cell come...

Problems solved by technology

However, the above-mentioned hydrogen production device for electric vehicles also has the following deficiencies: First, since the hydrogen production device is a device that decomposes fuel containing organic matter (such as methanol) at a temperature of 30-90 ° C to produce hydrogen-containing gas, and relies on oxidation Therefore, the conversion rate of organic matter into hydrogen is slow, and the efficiency of organic matter into hydrogen is actually not high, and the utilization rate of organic matter is low; Purification of hydrogen gas into high-purity hydrogen at relatively low temperature is inefficient and expensive, and requires a large-volume purification device in exchange for the normal supply of high-purity hydrogen, which is not conducive to the miniaturization of hydrogen manufacturing devices.
