NGK SPARK PLUG CO., LTD. (President and CEO: Shinichi Odo, Headquarters: Mizuho-ku, Nagoya, JAPAN hereafter the “Company”) is pleased to announce that the Company has released a hydrogen leak detection sensor for Fuel Cell Vehicles (FCV) .
FCV is expected to be a next-generation vehicle, while the hydrogen leak is highly concerned. It is indispensable to detect the hydrogen leak with reliability and precisely to secure safety driving. The hydrogen leak detection sensor alarms the driver and informs the slight hydrogen leak from the fuel cell system such as a hydrogen tank or a stack to stop the supply of hydrogen to the fuel cell.
The hydrogen leak detection sensor adopts a new detection method called "heat conduction", and it enables to detect the hydrogen leak precisely by measuring the amount of heat which the hydrogen takes from the heater in the sensor. Furthermore, it has features of quick activation, quick response, shock resistance and little aging deterioration since this method does not use a chemical reaction.
We have been developing the hydrogen leak detection sensor for FCV since 2006, and we have just released it.
We will strive to further expand sales of this hydrogen leak detection sensor, and contribute to the next-generation car society by bringing our technologies and ideas together.
