This work is to develop a new hydrogen purification and storage system for daily start and stop (DSS) operations. The new system enables us to minimize emissions of carbon dioxide by using compact and highly efficient fuel cells. The new system first removes carbon monoxide, which is poisonous to metal hydride, from reformed gas by using a special carbon monoxide adsorbent. After removing carbon monoxide, the reformed gas is introduced to a metal hydride bed to purify and store hydrogen. Some 100 NL/h Laboratory scale apparatus was operated in daily start and stop operations for 100 cycles for a total of 150 h with quite good efficiency. The new process has achieved an 83% hydrogen recovery ratio in one-month DSS operations.
► We demonstrate a new hydrogen purification and storage system.
► New system consists of CO selective adsorbent and AB5-type Metal hydride.
► 100NL/h Laboratory scale apparatus was operated for 150 h.
► The operation was conducted daily start and stop and achieved 83% H2 recovery ratio.
► The new system enables us to utilize pure hydrogen fuel cell system.
