MEMBRANE-ELECTRODE-GASKET ASSEMBLY FOR ALKALINE WATER ELECTROLYSIS

摘要

A membrane-electrode-gasket assembly for alkaline water electrolysis, the assembly including: a separating membrane having first and second membrane faces; a first electrode arranged in contact with the first membrane face; and an insulating gasket holding the membrane and the electrode as one body, the gasket including: first and second faces for contacting with anode- and cathode-side frames respectively; a slit part opening toward an inner side of the gasket and receiving the entire peripheries of the membrane and the electrode; first and second parts facing with each other across the slit part; and a continuous part arranged on an outer periphery side of the slit part, uniting the first and second parts into one body, and sealing an outer periphery end of the slit part, wherein the first and second parts sandwich therebetween to hold the entire peripheries of the membrane and the electrode received in the slit part into one body.
