Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a multi-combination independent alcohol-water hydrogen production 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 mate...

Problems solved by technology

[0005] (1) 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 the oxide electrode and the fuel electrode to generate hydrogen, therefore, the organic matter is converted into hydrogen The rate is slow, and the efficiency of converting organic matter into hydrogen is actually not high, and the utilization rate of organic matter is low;

[0006] (2) Purification of the hydrogen-containing gas produced by the hydrogen production device into high-purity hydrogen at a lower temperature is inefficient and expensive, requiring a large volume purification device in exchange for the normal supply of high-purity hydrogen, which is not conducive to the miniaturization of the hydrogen production device develop;

[0007] (3) For the electric vehicle disclosed in the above patent, regardless of the number of fuel cells, a single hydrogen production device is used to supply hydrogen to the fuel cells. In this way, the problems that arise are: 1. The volume of the hydrogen production device and the hydrogen production capacity The larger the volume, the larger the volume and hydrogen production capacity, the more difficult it is to start operation; 2. The hydrogen production device with large volume and hydrogen production capacity has poor stability and large vibration; 3. The hydrogen production device with large volume and hydrogen production capacity For the hydrogen production device, the control of parameters such as hydrogen production temperature, gas flow and air pressure is not sensitive enough; 4. The safety of a single hydrogen production device is low. When the hydrogen production device fails, the electric vehicle is paralyzed; 5. When a single When the hydrogen production capacity of the hydrogen production device is not enough, it is difficult to increase its hydrogen production capacity, and when the hydrogen production capacity is too large, it is difficult to reduce its hydrogen production capacity
