Monitoring of Impurity in Hydrogen Gas for FCV

• Impurities of ultra-low concentration cannot be measured.
• Want to perform continuous monitoring instead of batch measurement.
• Want to prioritize purity monitoring of carbon monoxide (CO) to monitor the quality of hydrogen gas itself and to identify the PSA performance.

   *PSA: Pressure Swing Adsorption

HORIBA's GA-370 trace gas analyzer can continuously measure impurities in hydrogen gases with high sensitivity. It can stably measure substances that are major causes of poisoning, including CO at a minimum detection sensitivity of 10 ppb and with a low range of 0 to 1 ppm.
The GA-370 can also measure up to two components, such as CO and CH₄, at the same time with a single unit. This will help to know the performance of PSA and timing to exhange the catalyst inside.

Features

• Improved stability by employing HORIBA's unique measurement technique (cross-flow modulation dual-beam non-dispersive infrared (NDIR) technique)
• The infrared system realizes a minimum detection sensitivity of 10 ppb.
• Low range measurement (0-1, 2, 5, or 10 ppm) is possible.
• It enables to measure up to two components in CO, CH₄ and CO₂.

• Hydrogen Quality Control at Hydrogen Production Plant

Trace Gas Analyzer GA-370 controls the quality of high-purity hydrogen gas, by monitoring the concentration of CO, CO₂ and CH₄ among the impurities generated in the hydrogen.  

• Process Monitoring of PSA during Hydrogen Purification 

In PSA during the manufacturing process, GA-370 monitors the concentration of impurities in real time.  It contributes to hydrogen quality control and reduction of manufacturing cost.  

• Hydrogen Quality Control at On-site Hydrogen Fueling Station 

Similar to hydrogen production plant, GA-370 monitors the concentration of CO, CO₂, CH₄ among the impurities generated in the hydrogen production equipment, at on-site hydrogen fueling station. Grasping these concentrations are significant because those would deteriorate the fuel cell of vehicles.
