Swedish researchers develop surplus rapid hydrogen leak detector

Reported that Chile's ambitious plans to control the capital Santiago serious smog problem, including commissioning electric small pedal motorcycle, electric cars and taxis, and mining industry use electric truck.

recently, Sweden, mustang China university of technology ( 查尔莫斯理工大学) Researchers have developed a sensor, it can overcome the hydrogen fuel cell transport, one of the biggest obstacles, when combined with hydrogen and oxygen gas to burn. The research results, to the development of hydrogen cars bring great leap forward.

with water as the only emissions of hydrogen, it as transportation energy advantage, no doubt, but as long as there is 4% of the gas and air mixture, it will produce highly flammable hydrogen gas, making hydrogen cars easily happened explosion at a high speed. Therefore, in order to make hydrogen transport, you need to have the most quickly, the most sensitive hydrogen leak detection system.

, mustang polytechnic university research team has been published in the journal nature materials its research & ndash; — They invented the first in the history of the air can be detected in a second 0. 1% hydrogen sensor.

scientists developed a optimized nanometer sensor, the detection of hydrogen leakage of the ability of the plasma, through wrapped in plastic shield around the suite has been enhanced. When the metal nanoparticles in the sensor is illuminated and capture the visible light, can produce plasma. Based on the plastic and the best balance between the sensor test, scientists can maximize response ability and sensitivity of sensors.

from Mr. Mustang polytechnic university department of physics, a researcher at the Ferry Nugroho said that they are not only developed the world's fastest hydrogen sensor, and this kind of sensor has a long-term stability, not failure. Unlike other hydrogen sensor, new sensors because of the protective plastic shield, so don't need regular calibration again.
