FIELD: production of porous gas-diffusion electrodes.
SUBSTANCE: porous system of silver catalyst is filled with wetting liquid; size of solid agent grain exceeds that of silver catalyst; they are mixed for forming homogeneous mass stable in compression; mass is molded in calender forming homogeneous catalyst tape; at second stage of calendaring electric conducting discharge material is rolled in catalyst tape.
EFFECT: possibility of producing electrodes with large pores for quick transfer of gas and small pores in catalyst.
