Releasing Time:2018-12-08
In Chengdu, CNG buses using clean energy can be seen everywhere, and there are more and more pure electric buses. Since April this year, hydrogen fuel cell buses have started to be used in the P09 bus line in Yandu District, Chengdu is in new energy. The bus sector is another city! This also means that Sichuan has become the second province in the country to carry out the commercial demonstration operation of hydrogen fuel cell buses after Guangdong.

This batch of hydrogen fuel cell buses was jointly developed by Yandu Bus and Dongfang Electric. It is a fuel cell bus based on core independent intellectual property rights. It meets the national new technical standards and is leading the country in terms of technology. The reporter learned yesterday that up to now, 10 hydrogen fuel cell buses on the line have been safely operated over 100,000 kilometers.

In addition, as the hydrogen fuel cell bus demonstration application supporting facilities, Chengdu's first temporary hydrogen refueling station was officially put into demonstration operation in Qidu District in February this year; at present, Sichuan Natural Gas Company is taking the lead and is building the first large-scale Chengdu city. Fixed hydrogen refueling station.

Starting in April, 10 vehicles safely traveled over 100,000 kilometers.

According to the Chengdu Bus Group, its holding subsidiary, Yaodu District Bus Bus Co., Ltd. (referred to as “Ziba Company”), has gradually invested in 10 hydrogen fuel cell buses on the P09 line since April this year. The starting and ending point of the line is Tangdu Town, the passenger transportation center station of Yaodu District. The whole journey is 52 kilometers, and each vehicle runs more than 200 kilometers per day.

Yang Jianbo, chief designer of Yandu Bus, said that these hydrogen fuel cell buses are hydrogenated on average every two days, each time taking more than 10 minutes. As of July this year, the first batch (two bicycles) operated an average of more than 25,000 kilometers, the second batch (four vehicles) had an average mileage of 8,000 kilometers, and the third batch (four vehicles) had an average mileage of more than 4,000 kilometers. The mileage has exceeded 100,000 kilometers. He told reporters that after a period of running-in, the driver was comfortable and comfortable to drive, and the passengers also reported that they were quiet and stable.

The hydrogen refueling station is an auxiliary facility for demonstration applications of hydrogen fuel cell buses. The reporter learned from the Chengdu Economic and Information Committee that in February this year, the first temporary hydrogenation station in Chengdu was officially put into demonstration operation in the Qitu area, which can meet the normal hydrogenation of five hydrogen fuel cell buses. At present, Sichuan Natural Gas Company is taking the lead and is building the first large-scale fixed hydrogen refueling station in Chengdu.

Hydrogen fuel cell bus on the streets of Chengdu’s Batu, only draining and exhausting

Self development

Fill up once and hydrogen can run 600 kilometers

Yesterday, the reporter saw a hydrogen fuel cell bus at the Yudu Bus Factory. “The car is 9 meters long and has a total of 27 seats, which can accommodate up to 70 people.” Yang Jianbo introduced that this batch of hydrogen fuel cell buses was jointly developed by Yandu Bus and Dongfang Electric. It is a fuel cell bus based on independent core intellectual property rights. Yandu Bus mainly focuses on vehicle design and key component integration. The core technology of hydrogen fuel cells is dominated by Dongfang Electric Qingneng. Six hydrogen storage tanks are placed on the roof, and the maximum hydrogen storage weight is 21kg. Filled with hydrogen once, running mileage over 500 kilometers, plus battery-assisted energy, the longest cruising range can reach 600 kilometers. The battery-assisted energy is installed on the lower right side of the vehicle, and it can travel 80 to 100 kilometers in an emergency without hydrogen fuel.

Yang Jianbo said that instead of burning, hydrogen fuel uses electrochemical reactions to convert the chemical energy of hydrogen into electrical energy and then drive the vehicle through a motor. He opened the vehicle's reserve compartment. The blue pipe was the air pipe. The silver pipe was the hydrogen pipe. After the oxygen and oxygen in the air entered the stack, the electric energy was generated by the electrochemical reaction with the help of the catalyst to drive the vehicle to run. "The fuel cell's power generation efficiency can reach more than 50%, and the internal combustion engine is 30% to 40%." When the driver brakes on the brakes, the kinetic energy is converted into electric energy and stored in the vehicle's power battery.

Complete zero pollution

Only draining and exhausting during driving

The reporter saw that there are two pipes at the bottom of the car, but this is not the exhaust pipe, but the drain pipe. Yang Jianbo said that the hydrogen fuel cell bus only emits clean water during the driving process and is completely zero-pollution. "Water can also be introduced to the vicinity of the tires to suppress dust during driving and further reduce pollution."

With the advancement of technology, problems such as safety and hydrogen fuel storage technology that have plagued the development of hydrogen fuel cells have gradually been overcome and improved. Yang Jianbo pointed to a small black box in the reserve cabin. This is the sensor, which can detect the hydrogen leak in the first time and alert the driver. The driver can safely dispose of it at the time or afterwards. Even if it is not disposed, the safety system can control the valve to automatically close as the gas concentration rises.

The hydrogen storage tank of the vehicle has undergone rigorous testing, and fire and gunshots are not damaged. And because it is located on the roof, even if a leak occurs, the hydrogen is very light and is quickly released into the atmosphere, causing no accumulation and injury to passengers. The reporter learned that the development of hydrogen fuel cell vehicles is currently facing high cost. In this regard, Yang Jianbo believes that as performance continues to increase, economic costs will tend to be reasonable within a few years. In terms of technology, the power density of the stack is further increased, the volume and weight of the stack are reduced, the amount of auxiliary batteries is reduced, and the space of the vehicle is increased.
