In recent years, electric vehicles have frequently caused safety accidents. There are not a few accidents such as the sudden explosion of electric vehicles in the elevator and the instantaneous deflagration of lithium battery indoor charging. The safety of household electric equipment has increasingly become the focus of public attention. Recently, Xiaokang China Xiaokang Network interviewed Chai Maorong, chief hydrogen energy expert of the State Power Investment Group and chief hydrogen energy model engineer of the State Power Investment Group, on the safety of electric tools. Chai Maorong believed that small hydrogen cars may be the way to break the situation.

As an internationally renowned fuel cell expert, Chai Maorong is committed to researching and promoting fuel cell technology and is active in the forefront of fuel cell technology. It has mastered the fuel cell catalyst, metal dispersion and other related technologies, in the international leading level. In the past 5 years, his team has made a series of breakthroughs in clean energy technology research and development and industrial project implementation, including catalysts, proton membranes, carbon paper, membrane electrodes, bipolar plates, stacks, systems, air compressors and hydrogen Ejector, "Hydrogen Teng" fuel cell......

In the 52 days of serving the Winter Olympics, the State Power Investment Group has put in a total of 200 hydrogen buses (50 of which are in standby), dispatched 6842 trains, transported 150413 people, operated 793000 kilometers, reduced carbon emissions by 550 tons, and completed all operation tasks with zero failure and zero accident. The hydrogen fuel cell engine, the core of the hydrogen bus, was developed by Chai Maorong.

According to Chai Maorong, in the field of transportation, hydrogen energy is widely used. Japan's fuel tram passenger car can run more than 1000 kilometers after charging for 3 minutes, and can run further in winter. He believes that my country needs to vigorously develop passenger cars first, starting with the development of passenger cars; only by developing passenger cars can the volume increase and the cost can be reduced. Fuel cell vehicles and passenger cars are inescapable roads, because they have the electronicization of electric vehicles and the inverter of fuel vehicles, which is equivalent to an electric vehicle in front and a fuel vehicle in the back. It is such a set of devices, so it has the advantages of high safety, low cost and fast "hydrogen" speed of fuel vehicles, as well as the reliability, long life and high environmental adaptability of electric vehicles, from minus 40 ℃ to minus 60 ℃, the whole working range is very wide, and the acceleration and start-up are very fast, which is the biggest feature. Chai Maorong suggested that my country should speed up the liberalization of the passenger car market, and improve safety and reliability through large-scale cost reduction and technical iteration. This is a very important point.
