These are great suggestions.

Have you looked at the hydrogen gas association website for guidance?

I believe the URL is
At one point the website was set up 
with application-specific modules,
such as hydrogen fuel cells.

In trying to verify that information, I found a link to the Fuel Cell and Hydrogen Energy Association (
Perhaps FCHEA can provide you with 
design best practices?

It turns out FCHEA resulted from the merger of the National Hydrogen Association and the U.S. Fuel Cell Council.

Good luck,

Make sure that you're compliant with NFPA 55 and sensors are located at/near point of use and in the ceiling and high points in the facility.  Whatever your fire marshal recommends for area coverage, double it and change the sensors out twice as often as recommended by the manufacturer as gas sensors are very susceptible to environmental degradation.

My apologies, it is a 2 sensor system, H2 and O2.


Thank you for asking/clarifying the question.

I would also use a room O2 sensor for the room.  It helps the team to know if oxygen levels are slipping to dangerous levels because of a H2 leak.

I have a researcher who is intending to start work on a hydrogen fuel cell. I want to make sure I have covered all the bases when I talk with him. The hydrogen sensor has already been purchased, but if you can provide any extra guidance, that would be great.


Thank you,
