The problems of environmental pollution caused by the consumption and emission of earth resources are more and more prominent. All the resources with serious pollution are gradually replaced by clean energy in the future.
In recent years, research and development and production of clean energy vehicles or hybrid energy vehicles have been underway, but there are many problems in terms of safety, reliability, endurance, and the like.

The energy density of the liquid methanol is only slightly lower than that of common gasoline and diesel oil, and the existing fuel tank on the automobile can be used for containing the liquid methanol; by the same principle, liquid methanol can be quickly filled through a traditional gas station, so that the hydrogen with low specific energy density has great advantages when being applied to a fuel cell, the automobile can easily carry the amount of the liquid methanol covering enough mileage, and the quick filling is convenient. In addition, in the aspects of saving earth resources and reducing carbon emission, methanol can also be made of biofuel, so that the methanol fuel has great advantages compared with the traditional petroleum fuels such as gasoline, diesel oil and the like. Compared with hydrogen, the liquid methanol can be very conveniently filled in a traditional fuel tank, the liquid methanol can be easily carried on a vehicle to cover enough mileage, and the liquid methanol can be quickly filled in a traditional gas station. In the aspect of safety, the liquid methanol has lower ignition point and is safer than the traditional gasoline, diesel oil and hydrogen.
The fuel tank 21 is divided into two paths by a pipeline, and each path is respectively communicated with two fuel cell stacks of the fuel cell system 9 through an electromagnetic control valve 11; the two Fuel Cell stacks are a main Fuel Cell stack 3 based on Solid Oxide Fuel cells (SOFC-Solid Oxide Fuel Cell) and an auxiliary Fuel Cell stack 4 based on Direct Methanol Fuel cells (DMFC-Direct Methanol Fuel Cell), respectively.

When the automobile is in a standby state, the control system 1 regulates and controls the electromagnetic control valve 11 at the front end of the auxiliary fuel cell stack 4 to provide a controllable small amount of liquid methanol for the auxiliary fuel cell stack 4 to generate a small amount of electric energy; when the automobile needs to be started, the control system 1 regulates and controls the electromagnetic control valves 11 at the front ends of the main fuel cell stack 3 and the auxiliary fuel cell stack 4, supplies a large amount of controllable liquid methanol to the auxiliary fuel cell stack 4 and the main fuel cell stack 3, instantly generates starting electric energy, and supplies the starting electric energy to an automobile power system through the voltage conversion device 6.

The fuel cell power plant 8 allows the entire vehicle system to be operated at a high power density and optimum energy efficiency.
When the automobile is started, the automobile control terminal sends a real-time power demand signal, the control system 1 in the fuel cell power supply device 8 receives the real-time power demand signal, and starts to regulate and control the electromagnetic control valve 11 installed at the output end of the fuel tank 21, and regulates and controls the release parameters (including release time, release flow and the like) of the liquid methanol, so that the liquid methanol enters the auxiliary fuel cell stack 4 based on the direct methanol fuel cell and the main fuel cell stack 3 based on the solid oxygen fuel cell in a time-sharing and fractional manner, and the electric energy required by the integral operation of the automobile is generated. In the present embodiment, the fuel tank 21 supplies liquid methanol in two paths to the two fuel cell stacks via the respective electromagnetic control valves 11. In practical application, the fuel tank 21 may have only one output, and the liquid methanol may be controllably supplied to the two fuel cell stacks through a three-way structure.
