HYDROGEN GENERATING DEVICE AND HYDROGEN GENERATING UNIT, AND ENERGY SYSTEM USING SAME

WIPO Patent Application WO/2014/128813

A1

Provided are a hydrogen generating device and hydrogen generating unit, and an energy system using the same, in which a plurality of hydrogen generating cells are disposed in a positional relationship having a difference in elevation, and are connected in series as viewed from a liquid electrolyte flow, whereby the problems of mixing of generated hydrogen and oxygen, polarization due to adhesion of bubbles on an electrode surface, and fluid pressure of the liquid electrolyte are simultaneously overcome. In the hydrogen generating device, liquid electrolyte flow channels between the plurality of hydrogen generating cells constituting the device are provided separately for a hydrogen generating side and an oxygen generating side. Between the plurality of hydrogen generating cells, a liquid electrolyte flow channel through which the liquid electrolyte flows is formed leading from top to bottom, whereas inside the hydrogen generating cells, a liquid electrolyte flow channel through which the liquid electrolyte flows is formed leading from bottom to top. A point of contact with generated gas or the atmosphere is furthermore provided in a path of the liquid electrolyte flow channels.
