The HB-SC-50 liter Hydrogen Fuel Cartridge is designed to be used as a standard hydrogen fuel gas storage for our portable FID based instrument and to act as a back up hydrogen source at room temperature. This hydrogen storage system is based on the latest achievements in solid metal hydride technology of AB5-type alloys as well as on unique techniques of alloy loading. It allows to store and release the gas at ambient temperature and at designed pressure range from 1.0 up to 10.0 ATM with very high stability of gas flow: 95% of the stored gas can be released with designed maximum flow rate at constant temperature.
