This makes new sensors don't need to attached in high temperature heater, photovoltaic power generation operation mode its application value. Hydrogen fuel is commonly used now in many places the new energy. The process of monitoring it takes about 25 seconds. According to introducing, some hydrogen sensor need about 250 degrees Celsius temperature to activate the relevant chemical reaction, but the new sensor due to join the carbon nanofibers, furniture back images can achieve the same effect at 150 degrees Celsius. According to introducing, hydrogen concentration in the environment of 100 PPM ( 1 PPM is one over one million) The detection sensitivity of the sensor can reach 74%. Substation contract that install photovoltaic process jodhpur Indian institute of technology, institutions such as researchers in the Netherlands academic journals 'sensors and actuators B: chemical' on the relevant papers published. Indian researchers have recently developed a kind of high sensitive sensor, it can detect under the condition of low concentration of hydrogen, is expected to be in the place where some use of hydrogen fuel used to detect if there is a hydrogen gas leak. Due to hydrogen colorless, tasteless, leak detection in the environment of hydrogen is generally more difficult. Substation process researchers using zinc oxide resistance changes when in contact with hydrogen material, such as the principle to design the sensor. Hydrogen although there is no pollution, but it is flammable and explosive, so need to prevent leakage.
