Abstract
The present invention provides a method of fixing a separator membrane to a first frame member of a battery cell stack. The method comprises: creating a fixation area comprising a first zone and a second zone, wherein creating the first zone comprises securing the separator membrane to the first frame member, and wherein creating the second zone comprises mechanically compressing the separator membrane with a projection of a frame member or with a sealing part. There is also provided a cell stack and a use of an ion-exchange membrane in the disclosed cell stack.
Claims17
A method of fixing a separator membrane to a first frame member of a cell stack, the method comprising:
- creating a fixation area comprising a first zone and a second zone,
- wherein creating the first zone comprises adhering or integrally bonding or a combination of adhering and integrally bonding the separator membrane to the first frame member, and
- wherein creating the second zone comprises mechanically compressing the separator membrane with a projection of a frame member.
A cell stack comprising:
- at least one of:
- a separator membrane fixed to a first frame member, wherein the fixation area comprises a first zone and a second zone, the first zone comprising the separator membrane adhered and/or integrally bonded to the first frame member, and the second zone comprising the separator membrane mechanically compressed by a projection of a frame member;
- and
- a pair of electrode assemblies, wherein the separator membrane fixed to the first frame member is provided between the pair of electrode assemblies;
- and
- an electrically-isolated end plate in an adjacent layer to each outermost electrode assembly,
- wherein the layers of the cell stack are fastened together.
