Allengra's Hydrogen Flow Meter is tailored to bring solutions to a wide range of hydrogen and different types of gas mixture-related issues, via Ultrasonic Technology.  

Allengra’s Hydrogen Flow Meter can offer: 

• Density and Mass Flow: Accurate measurement of both mass flow and gas concentration for optimized efficiency and lifespan. 

• Comprehensive Data: Real-time data on volume flow, temperature, humidity, and pressure for precise anode recirculation control. 

• Ideal Hydrogen/Nitrogen Ratio: Precise concentration readings for optimal fuel cell performance and longevity. 

Hydration and Anode Circulation in PEM Fuel Cells   

By using Allengra’s Hydrogen Flow Meter, the anode gas from the stack outlet can be recirculated back to the stack inlet. This process saves the excess hydrogen from being unnecessarily wasted, thereby increasing the efficiency of the fuel cell, as there is more hydrogen available for the electrochemical reaction.
