METHOD OF ABSORPTION-DESORPTION OF HYDROGEN STORAGE ALLOY AND HYDROGEN STORAGE ALLOY AND FUEL CELL USING SAID METHOD

摘要

According to the invention, hydrogen absorbed in a PCT curve low pressure region not desorbed and utilized so far can be desorbed easily by controlling a hydrogen storage alloy temperature in the final stage of a hydrogen desorption process (T2) to a temperature higher than the hydrogen storage alloy temperature in the hydrogen absorption process (T0) and a hydrogen storage alloy temperature in the initial stage of the hydrogen desorption process (T1) (T2 > T1 >/= T0).
