A method for producing a laminate of an electrode for electrolysis and a membrane, comprising:
- rolling out an elongate electrode for electrolysis from a roll for electrode around which the electrode for electrolysis is wound, and
- rolling out an elongate membrane from a roll for membrane around which the membrane is wound.
13-16. (canceled)
A package comprising:
- a roll for electrode around which an elongate electrode for electrolysis is wound and/or a roll for membrane around which an elongate membrane is wound, and
- a housing storing the roll for electrode and/or the roll for membrane.
A laminate comprising:
- an electrode for electrolysis, and
- a membrane laminated on the electrode for electrolysis, wherein
- the membrane has an asperity geometry on the surface thereof, and
- a ratio a of a gap volume between the electrode for electrolysis and the membrane with respect to a unit area of the membrane is more than 0.8 μm and 200 μm or less.
22-27. (canceled)
A method for producing a new electrolyzer by arranging an electrode for electrolysis in an existing electrolyzer comprising an anode, a cathode that is opposed to the anode, a membrane arranged between the anode and the cathode, and an electrolytic cell frame comprising an anode frame that supports an the anode and a cathode frame that supports the cathode, the electrolytic cell frame storing the anode, the cathode, and the membrane by integrating the anode frame and the cathode frame, the method comprising:
- a releasing process (A1) of releasing the integration of the anode frame and the cathode frame to expose the membrane,
- an arranging process (B1) of arranging the electrode for electrolysis on at least one of surfaces of the membrane after the releasing process (A1), and
- an integrating process (C1) of integrating the anode frame and the cathode frame after the arranging process (B1) to store the anode, the cathode, the membrane, and the electrode for electrolysis into the electrolytic cell frame.
