POROUS HYDROPHILIC DIAPHRAGM AND THE METHOD OF ITS PRODUCTION

摘要

FIELD: chemical industry; methods of production of the porous hydrophilic diaphragms. ^ SUBSTANCE: the invention is pertaining to the process engineering of production of the porous hydrophilic diaphragms with the high water permeability and may be used in production of the fuel cells or electrochemical cells with the high electric conductivity. The porous hydrophilic diaphragm includes the porous inertial substrate on the basis of (per) fluorinated polymer, on which the ion meter in the amorphous state is deposited representing the (per)fluorinated polymeric compound having the hydrophilic groups in the acidic form. The produced diaphragms have the water permeability exceeding 1 l/(h.m2.atm) and possesses the ion conductivity. ^ EFFECT: the invention ensures production of the porous hydrophilic diaphragms with the high water permeability, electric and ion conductivity. ^ 40 cl, 9 ex
