MANUFACTURING METHOD OF BARRIER FOR ALKALINE WATER ELECTROLYSIS, AND BARRIER FOR ALKALINE WATER ELECTROLYSIS

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a barrier for alkaline water electrolysis, the barrier having excellent ion permeability and chemical resistance and on the surface of which gas generated at an electrode in electrolysis is difficult to adhere.SOLUTION: A manufacturing method of a barrier for alkaline water electrolysis includes: a step of preparing a resin composition including epoxy resin, a curing agent and porogen; and a step of preparing a resin sheet using the resin composition. In one embodiment, the manufacturing method of a barrier for alkaline water electrolysis further includes a step of removing the porogen from the resin sheet.
