Abstract
Cycling performance of hydrogen storage LaNi5-x alloys under O-2 and H 2O was investigated to develop a hydrogen storage system connected wit h a solid polymer electrolyte water electrolysis device. The best Al c ontent was found to be between 0.5 and 0.8 through analysis of the ini tial hydrogen storage capacity decaying curves measured under impure h ydrogen gas containing 100 ppm of O-2, introducing a criteria for maxi mizing the total amount of hydrogen storage for long-term utilization of up to 10 000 cycles.
