Claims (8)

1. Elektrolysestak (2) til et elektrolyseanlæg (20), hvilken elektrolysestak (2) omfatter flere elektrolyseceller, som hver omfatter to elektroder og en gassepareringsmembran og en celleramme (6, 6', 6"), hvilke cellerammer (6, 6', 6") er anbragt ved siden af hinanden og mellem to flanger (24, 24'), hvilken elektrolysestak (2) omfatter midler (18) til forsyning af elektrolytter til det indre af elektrolysecellerne og midler (16) til at fjerne oxygengas og hydrogengas fra elektrolysecellerne, hvilken elektrolysestak (2) omfatter elektriske strømelementer (46, 46', 48, 48'), der udgør enten en katode, en anode eller en katode og en anode, kendetegnet ved, at elektrolysestakken (2) omfatter flere forstærkningselementer (12, 12', 42, 42', 42"), som er anbragt med indbyrdes ende-mod-ende-kontakt og i en i det væsentlige aksial forlængelse af hinanden, idet disse forstærkningselementer er anbragt på cellerammernes (6, 6', 6") ydre periferi på en sådan måde, at de ikke er i mekanisk kontakt med flangerne (24, 24'), og hvor flangerne (24, 24') er mekanisk forbundet med hinanden ved hjælp af flere gevindstænger (26) og tilhørende møtrikker (22) og skiver (44).
2. Elektrolysestak (2) ifølge krav 1, kendetegnet ved, at elektrolysestakken (2) er inddelt i flere elektrisk adskilte cellerammemoduler (Mi, M2, M3).
3. Elektrolysestak (2) ifølge krav 1 eller 2, kendetegnet ved, at forstærkningselementerne (12, 12', 42, 42', 42") er cylindriske og strækker sig langs cellerammens (6, 6', 6") aksiale længde.
4. Elektrolysestak (2) ifølge et af de foregående krav, kendetegnet ved, at forstærkningselementernes (12, 12', 42, 42', 42") elasticitetsmodul er højere end cellerammernes (6, 6', 6") elasticitetsmodul.
5. Elektrolysestak (2) ifølge et af de foregående krav, kendetegnet ved, at forstærkningselementernes (12, 12', 42, 42', 42") varmeudvidelseskoefficient er lavere end cellerammernes (6, 6', 6") varmeudvidelseskoefficient.
6. Elektrolysestak (2) ifølge et af de foregående krav, kendetegnet ved, at forstærkningselementet (12, 12', 42, 42', 42") er lavet af et elektrisk isolerende materiale, f.eks. et fiberforstærket plastmateriale.
7. Elektrolysestak (2) ifølge et af de foregående krav, kendetegnet ved, at elektrolysestakken (2) omfatter et første forstærkningselement (12) og mindst ét yderligere forstærkningselement (12', 42, 42', 42"), som er anbragt på ydersiden af det første forstærkningselement (12).
8. Elektrolyseanlæg (20) som omfatter en elektrolysestak (2) ifølge ethvert af kravene 1-7.
