Abstract
Each unit cell of a water electrolysis apparatus includes a pair of an anode separator and a cathode separator and a membrane electrode assembly interposed between the pair of separators. The anode separator has a first flow field to which water is supplied, and the cathode separator has a second flow field for producing high-pressure hydrogen through electrolysis of the water. A second seal groove for receiving a second seal member is disposed annularly around the second flow field. A pressure-releasing chamber is disposed outwardly of the second seal groove, is capable of communicating with the second seal groove and communicates with the outside through a depressurizing channel.
