Fueling Tomorrow with Confidence: The Safe Handling of Hydrogen in FCVs, the New Cosmos Electric Solution

Gearing up for a cleaner, greener future? FCEV (Fuel cell electric vehicles) are capturing hearts with their water-vapor-only emissions, but let's address the hydrogen in the room - is it safe?

Hydrogen, being lighter than air, tends to disperse quickly if there is a leak. However, the stakes are high, since, with a wide explosion range from 4% to 75%, hydrogen is highly combustible, and can be dangerous in enclosed spaces.?

That's where hydrogen detection comes into play. H2 sensors keep a watchful eye on the entire fuel storage and delivery system, ensuring the safety of hydrogen-powered vehicles – from cars and race cars to trucks, buses, ships, forklifts, tractors, trains, military vehicles, and even airplanes – and everyone around them.

Discover this unique hydrogen sensor used in the Toyota Mirai.?

New Cosmos Electric Co., Ltd. supplies the hydrogen detectors for Toyota Motor Corporation's from the end of 2020.

For the MIRAI, New Cosmos Electric uses a catalytic combustion sensor. The CSD-02 uses PWM output, but a CAN output version called CSD-04 will also be available soon (sample’s currently available). This sensor achieves both high sensitivity and long-lasting durability thanks to our proprietary catalyst technology. New Cosmos Electric`s experience in mass-production and investments in production capacity will ensure a steady supply of these vital safety components.

Leading the Way in Hydrogen Safety

New Cosmos Electric has a long history of developing innovative gas detection technology. With more than 60 years of experience, New Cosmos Electric remains at the forefront of hydrogen detection, chosen by 80% of Japanese hydrogen refueling system.

Ensuring Safety Throughout the Drive

The hydrogen detector is strategically placed above the vehicle's hydrogen tank or fuel cell stack. This positioning allows for the rapid detection of any potential hydrogen leaks, enhancing overall safety during operation.

Here's a glimpse of how our safety equipment protects FCEVs:

• Strategic sensor placement: the modules are located around the forward component and the hydrogen tanks, there they directly monitor for leaks.

• Safety measures spring into action: In the case of the Toyota Mirai, as a leak is detected, the sensor emits an electrical signal. The car reads this signal and takes appropriate measures, such as a warning lamp, venting the leaked gas, or shutting off the hydrogen gas in the system.
• Lightning-fast response: With its ability to detect hydrogen from 0 to 100% LEL in less than 3 seconds, New Cosmos Electric’s CSD is able to prevent accidents and ensure the safety of users.??
