Research and development of hydrogen energy safety

Hydrogen has been recently utilized in many fields due to its recyclability and non-pollution characteristics. Hydrogen fuel cell vehicles and hydrogen refueling stations have become the main carrier of hydrogen energy application. However, due to the inflammable and explosive characteristics, the safety problems of hydrogen became indispensable. This paper introduces the safety problems and countermeasures of hydrogen fuel cell vehicles and hydrogen refueling stations. The research progress and achievements of hydrogen energy standards are then comprehensively discussed. Finally, the development status, existing problems and future development direction of five kinds of optical fiber sensors are pointed out.
