METHOD FOR OPERATING AN ELECTROLYTIC CELL
A method for operating an electrolytic cell for electrolytic water splitting in which at least one membrane is supplied with water in a passive manner.
1 . A method for operating an electrolytic cell for electrolytic water splitting, the electrolytic cell comprising:
at least one membrane, wherein
the at least one membrane is supplied with liquid water in a passive manner.
2 . The method according to claim 1 , wherein
in at least one method step, water is distributed within the membrane by means of a channel structure formed in the at least one membrane.
3 . The method according to claim 1 , wherein
in at least one method step, water is introduced into the membrane, without a pump, from a water reservoir by means of a capillary effect of at least one cavity structure of the at least one membrane.
4 . The method according to claim 3 , wherein
in the at least one method step, water is introduced into the membrane with a capillary pressure of at least 25 mbar.
