China's first self-developed hydrogen-powered urban?train completedoperational tests on March 21 in Changchun, Jilin?province in northeast China, marking a breakthrough in the hydrogen application in rail transition.
On a test track, it achieved a full-system, full-scenario and multi-level performance verification at a speed of 160 km per hour.
The train, developed by CRRC Changchun Railway Vehicles, uses a hybrid power supply scheme to improve energy efficiency. Its hydrogen energy propulsion system provides a strong and long-lasting power source.
Test data showed that the average energy consumption per kilometer of the train is only 5kWh/km, and and the maximum cruising range is more than 1,000 kilometers.
The actual performance of the hydrogen train at -25℃ to 35℃ ambient temperature has been verified?by researchers,?and all the test results meet the design requirements.
The trio will conduct a series of experiments in fields such as life science, fluid physics, combustion science and materials science. Notably, this is the first time that fruit flies have been taken on a Chinese space mission as experimental subjects. What made scientists choose fruit flies? What experiment will they undergo?
