Abstract

En forbedret fremgangsmåte for tilveiebringelse av hydrogen fra en elek- trolytisk celle med en anolyttløsning som har et anolyttvæskenivå; en katolyttløs- ning som håret katolyttvæskenivå; generering av oksygen ved etoksygentrykk over anolyttnivået; generering av hydrogen ved et hydrogentrykk over katolytt- nivået; idet forbedringen omfatter påvisning av minst ett anolytt-væskenivå og katolytt-væskenivåene som anolyttnivå- og katolyttnivå-data; tilføring av nivådata til en sentral bearbeidingsanordning; bestemmelse av trykkforskjellen mellom nivåene utfra nevnte nivådata, og trykkjusteringsdata ved hjelp av den sentrale bearbeidingsanordning; og tilføring av reguleringsdata til trykkreguleringsanord- ningen for å opprettholde trykkforskjellen innenfor et valgt område. Fremgangs- måten tilveiebringer en lavkostmetode for regulering av trykkforskjellen til innen- for 2 cm vannsøyle av innstilt verdi.
