stration and development of hydrogen fuel systems to support FCVs.
Developed by CaFCP's cross-industry Inter-Operability Team, the HQSA allows a currently available gaseous fuel sampling bottle to be connected to an SAE-standardized hydrogen fueling station dispenser nozzle. Sampling can be conducted at the nozzle to identify possible contamination of the fuel after it has left the storage vessel. High hydrogen quality is important for obtaining optimal FCV performance.
Last year, the same CaFCP team developed a trailer-mounted hydrogen station testing apparatus (STA) [FCB, December]. The new HQSA has been incorporated into this mobile unit, allowing it to be transported easily to the growing network of hydrogen stations in California.
