    摘要： An electrochemical cell has a membrane located between two flow field plates. On a first side of the membrane, there is a porous support surrounded by a seal between the membrane and the flow field plate. There is a gap between the porous support and the seal at the surface of the membrane. On a second side of the membrane, there is a seal between the membrane and the flow field plate located inside of the gap in plan view. The electrochemical cell is useful, for example, in high pressure or differential pressure electrolysis in which the second side of the membrane will be consistently exposed to a higher pressure than the first side of the membrane.

    摘要： A differential pressure type high pressure water electrolysis apparatus includes a seal member, which is sandwiched between a cathode side separator and a membrane electrode assembly, and surrounds a cathode electrode catalyst layer, and a pressure resistant member surrounding the seal member from an outer side thereof. A surface pressure applying member is interposed between the seal member and the pressure resistant member. The surface pressure applying member receives a pressing force from the seal member, and applies pressure to the membrane electrode assembly.

    摘要： Among other things, a device for use in electrolyzing water is described. The device comprises an electrolysis unit that includes a chamber, an ion exchange structure in the chamber, a cathode, an anode, a high pressure chamber, and a reservoir. The chamber is separated by the ion exchange structure into a first compartment and a second compartment. The cathode is in the first compartment and the anode in the second compartment. The reservoir is disposed in the high pressure chamber for storing water to be supplied to the chamber of the electrolysis unit. In some implementations, the ion exchange structure is a proton exchange membrane.

    摘要： An electrolytic cell for generating hydrogen through the electrolysis of water, including an anodic compartment and a cathodic compartment separated by a solid polymeric electrolyte alkaline membrane. The anodic compartment includes a positive electrode or anode at least partially submerged in a layer of water, and the cathodic compartment includes a negative electrode or cathode. The cell is arranged between a first closing plate and a second closing plate. A tie-rod, provided in the central portion of the first closing plate, passes through the first closing plate, the cell and the second closing plate. A central collector for conveying the hydrogen generated in the cathodic compartment is arranged coaxially to the tie-rod and is in communication with the cathodic compartment through an opening formed in the tie-rod.
