Abstract
An electrochemical cell has at least one membrane strip that forms a central area and at least two, maximum 10,000 flat individual cells. The individual cells consist each of an electrode layer applied on both sides of a membrane made of a polymer solid electrolyte and of a corresponding number of flat electronically conductive areas. The individual cells are connected in series and the central area is provided with an appropriate periphery in the cell.
Claims19
An electrochemical cell assembly comprising:
- at least one strip membrane assembly having at least two substantially flat individual cells;
- each individual cell including a polymeric solid electrolyte membrane having a first and a second side, and an electrode layer being deposited on the first and second side;
- the polymeric solid electrolyte membranes of the individual cells being physically separated from each other;
- and
- electronically conductive regions electronically coupling the polymeric solid electrolyte membranes of the individual cells in series, such that the electrode layer on the first side of a first individual cell is electronically coupled to the electrode layer on the second side of an adjacent individual cell.
