A series of hydrogen absorption-desorption processes using a pellet form of Pd-Al2O3 was repeated up to 1010 cycles. Variations in the amounts and rates of hydrogen absorption and desorption with cycles were determined by means of a constant-volume method. The amounts and rates of absorption and desorption were almost unchanged up to 1010 cycles. The Scanning Electron Microscope pictures and Energy Dispersive Spectroscopy showed no microscopic change on the pellet surface after 1010 cycles. The experimental results assured a high tolerance of the Pd-Al2O3 pellet to repetitive absorption-desorption cycles.
