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.
HORIBA's GA-370 trace gas monitor 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.
