Demand for hydrogen, which has been attracting attention as a clean energy source, is expected to increase for energy applications in the areas of fuel cells and hydrogen gas turbines in addition to conventional industrial applications. ISO 14687-2 defines hydrogen quality standards for fuel cell vehicles, and failing to comply with these standards leads to poisoning of the catalyst and fuel cells.
*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.
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.
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.
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.
