Abstract
A method of fabricating an electrochemical or galvanic cell comprising a plurality of electrochemical components, which electrochemical components are joined together in a stack, which method comprises: i) providing a first component formed from a deformable polymeric material with at least one substantially continuous groove comprising a female opening having a width of 'w' and a depth of 'h'; ii) providing a second component with at least one substantially continuous upstand having a width of >'w' and a height of <'h'; iii) pressing the first and second components together in order to provide an integral seal between the upstand on the second component and the opening in the first component, with the seal between the parts being provided by sealing engagement of the sides of the upstand with the sides of the openings; and iv) joining a plurality of first and second components together to form a stack.
