Pressure Sensors for Fuel Cells
January 19, 2021
Fuel Cells are a green alternative to traditional gasoline or diesel-powered motion used in public buses, forklifts, refuse trucks, backup generators, etc. They are clean burning, give off no emissions and only have water as it’s by-product. One of the energy sources needed to run a fuel cell is hydrogen (the other is oxygen). In order for the fuel cell to run efficiently, the pressure in the hydrogen side of the system needs to be continuously monitored.
Challenge
Finding a pressure sensor that can withstand the harshness of hydrogen over extended periods of time
Hydrogen can attack and break down certain metals and make them brittle. This brittleness can cause the diaphragm to fail and leak. Leaking hydrogen into the atmosphere is very dangerous for it can be flammable. Also, if hydrogen accumulates in a confined area, it is an asphyxiant.
Solution
3500 Series Pressure Sensor
Utilizing 316L Stainless Steel, the Gems 3500 Series sensors are 100% compatible with Hydrogen Fuel Cell systems. This will lead to accurate pressure readings as well as a long-lasting solution for trouble-free operation.
