Water electrolysis using solar power is a key technology for producing green hydrogen. However, in many areas with high densities of solar radiation and stable weather conditions, for example arid regions, it is difficult to even access freshwater for daily life. On the other hand, even in the arid regions, the atmosphere contains a certain amount of water vapor. In this study, we investigated water electrolysis using water vapor from the air, specifically direct air electrolysis (DAE) using NaClO4 as a deliquescent neutral electrolyte salt and SiO2, Al2O3, MFI-type and LTA-type zeolite and TiO2 as reservoirs. After staying the DAE modules to remain in the air at ~83% relative humidity, the water vapor was captured by NaClO4 loaded onto all reservoirs, forming an electrolyte solution. The amount of water captured from the humid air increased with the increasing amount of NaClO4. Water electrolysis began after the stay in the humid air for 5 ~ 12 h in all cases. After water absorption for 20 h under 83%R.H., the current densities of DAE with Al2O3, MFI-type zeolite and TiO2 as reservoirs were comparable to that measured in NaClO4 aqueous solution. Water captured in TiO2 reservoir was efficiently electrolyzed even when less than 40 vol% of the reservoir was filled with the electrolyte solution. |
