A hydrogen production system according to an embodiment includes an evaporator that evaporates seawater to generate water vapor, an electrolytic device that electrolyzes the water vapor supplied from the evaporator to produce hydrogen, and a removal mechanism that is provided between the evaporator and the electrolytic device and removes a seawater component from the water vapor.

The present disclosure describes an apparatus that may be used to generate desalinated water from a supply of untreated water using a photovoltaic cell. The front surface of the photovoltaic cell is partially enclosed to form an evaporation chamber. The front surface of the photovoltaic cell is exposed to sunlight or another light source. This exposure results in power generation by the photovoltaic cell and also heats the air in the evaporation chamber. Untreated water is subsequently introduced into the evaporation chamber. Upon contacting the heated air and the front surface of the photovoltaic cell, a portion of the untreated water evaporates to generate water vapor. The water vapor is then removed from the evaporation chamber and transported to a condensation chamber. The water vapor is cooled in the condensation chamber to yield desalinated water.
