複極式電解槽、アルカリ水電解用複極式電解槽、及び水素製造方法
Document Type and Number:
Japanese Patent JP6746721
Kind Code:
B2
Abstract:
An object of the present disclosure is to maintain a superior electrolysis efficiency and higher purities of generated gases even during variable power source operations in a bipolar electrolyzer for alkaline water electrolysis using porous membranes containing inorganic particles as membranes. A bipolar electrolyzer for alkaline water electrolysis and a hydrogen production method include a bipolar electrolyzer including a plurality of combinations of an anode, a cathode, and a membrane disposed between the anode and the cathode, wherein the at least one of the anode or the cathode is a porous electrode having an average pore size of 10 nm or more and 200 nm or less, and the membrane is a porous membrane containing inorganic particles having an average primary grain size of 20 nm or more and 300 nm or less.
