Abstract

Elektrokjemisk celle lor reaksjon ;iv en væske med en gass, hvor : cellen hnr minst en dobbeltsidig (det vil si clcktrolyllakliv pfl begge sider) gassdiffusercnde elektrodeanordning som besiår av en porøs, selv-drenerende, gassdiffuserende elektrode med inlerm plassert elektrisk strømfordeler, all ¿ liokll summen i en ramme; s;imt en v;eske-permeabel mikroporøs membr;m i som st.lr i kontakt med de eksterne elektrodetl;itene med største ;ire;il. Den gassdiffuserende elektroden er fortrinnsvis en katode og er nyttig i en elektrokjemisk celleanordning i samstilling med to elektroder med moisiitt polaritet, fortrinnsvis anoder, som kan v;ere metallplater. Disse elektrodene (;modene) er plassert pS hver sin side av den gassdiffuserende elektrodeanordningen i samme elektrolytlrom. Elektrolytt tilføres cellen ved hjelp av pumpeanlegg. I en fordrukken utførelse blir elektrolytt i tillegg sirkulert inni rommet ved hjelp av turbulent elektrolyltslrømning som skyldes oppstigning av gassen som dannes ved elektrodene av motsatt polaritet under drift av cellen. En egenskap i en fordrukken uilørelse av den elekirokjemiske cellen i denne oppfinnelsen er regulen strømning av elektrolytt gjennom en flerlagsmembran slik ai "insulting" av elektroden ikke forekommer (øverst) og "oversvømmelse" av elektroden ikke forekommer (nederst). I "regulen strømning" ligger det at man sørger for en utjevning av de ulike strønmings- hastighelene øversl og nederst ved membranen over el bredt oinråde av elcktrolytt-væskestander.
