(WO9504382-A1)      An electrochemical cell with polymeric solid electrolyte has a core with a periphery, consisting of at least one strip membrane (5) contg. 2-10000 individual cell faces (6, 12, 13, 14) connected in series, each of which comprises a membrane (1) made of polymeric solid electrolyte (I) coated on both sides with an electrode layer (10).    USE -   E.g. as a fuel cell for traction applications.    ADVANTAGE -   Simpler and less expensive structure than prior-art cells, and a more reliable method of operation.
