[RenewableEnergyAccess.com] The California Fuel Cell Partnership (CaFCP) has developed a new tool to help facilitate the demonstration and development of hydrogen fuel systems to support fuel cell vehicles. CaFCP’s InterOperability Team developed the Hydrogen Quality Sampling Adaptor (HQSA) because of the importance of sampling the fuel at the point where it is dispensed into a vehicle’s tank. Just as conventional fuels used in cars and buses today must meet certain quality specifications, the quality of hydrogen is important for obtaining optimal performance of a fuel cell vehicle. Typically, hydrogen gas is sampled for quality testing at a fuel station’s storage vessels. With the new device, sampling can be conducted at the nozzle to identify possible contamination of the fuel that might occur after it has left the storage vessel. The InterOperability Team is a collaborative team of engineers and technical specialists from the multiple industry sectors that comprise the CaFCP membership. They are developing a number of tools to address various aspects of hydrogen quality to help fuel cell vehicles and hydrogen infrastructure advance towards full commercial status.
