| 内容記述 | Alkaline water electrolysis was performed using Ni(OH)2/NiOOH as an anode and MmNi5-based hydrogen storage alloy as a cathode removed from NiMH batteries at 303 K and 10 mA/cm2 for 2 h. The water decomposition voltage changed from 1.36 V to 1.48 V (thermoneutral voltage: 1.48 V). The hydrogen evolution reaction (HER) overpotentials of the practically used MmNi5-based alloy with low H2 dissociation pressure 0.012 MPa were small (33–75 mV) at 10 mA/cm2. The HER overpotentials were similar to those of Pt-based electrocatalysts. The low dissociation pressure of the hydride was suggested to play a key role to decrease the HER overpotentials of the alloy. The alkaline water electrolysis voltage was 1.46–1.48V and stable at 50 mA/cm2 and 353K for 24h. Then, the MmNi5-based hydrogen storage alloy was found to be a new type of HER electrocatalyst for alkaline water electrolysis. | |||||||||||
