ABSTRACT:
An electrochemical cell stack is made from a continuous laminate web including an electrode layer, an electrolyte layer, and a plurality of discrete opposite polarity electrode segments. The laminate is fan-folded into a stack such that substantially the entire surface area of the opposite polarity electrode segments are in contact with the electrolyte layer and in ion exchange with the electrode layer. Current can collected from the discrete opposite polarity electrode segments by opposite polarity electrode current collector strips that electrically connect the opposite polarity electrode segments. A method for making an electrochemical cell stack is also disclosed.
