2021/3/1 New Product

NEW COSMOS ELECTRIC CO., LTD. (JASDAQ listing: Securities code 6824; Address: 2-5-4 Mitsuyanaka, Yodogawa-ku, Osaka; Tel: 06-6308-2111; President: Yoshinori Takahashi; Capital: 1,460 million yen) Has started supplying hydrogen detectors for the new “MIRAI” fuel cell vehicle, which Toyota Motor Corporation began selling in December 2020.

Development history

We have developed a unique sensor with excellent hydrogen selectivity and have used it in various gas detectors and alarms. The catalytic combustion sensor used for the hydrogen detector this time has both high response and high durability by the catalyst technology has achieved both high response and high durability by the catalyst technology originally developed by our company. In addition, we will realize a stable supply of gas sensors with mass production technology cultivated over many years by manufacturing household gas alarms.
The hydrogen detector is mounted on the top of the tank or stack as a hydrogen safety component.

How it works on FCV

The hydrogen detector verifies that there are no hydrogen leaks from system startup to shutdown and that the valve is closed properly.
Hydrogen detectors are installed in the front compartment and hydrogen tank for monitoring, and if a hydrogen leak above a certain concentration is detected, a warning light in the meter will notify you.

Our goal

We also sell gas detection and alarm systems for hydrogen stations, and our products are used in about 80% of hydrogen stations in Japan. There is also growing demand for portable gas detectors used to inspect pipes and equipment.
We will continue to support the development and safety of the hydrogen society through the sale of various products that “detect and notify hydrogen.”
