An electrochemical cell (10) comprising a working electrode (11) and a counter-electrode (12) provided on flexible polymeric substrates (13, 18) is disclosed. The working electrode comprises an electrically conductive film, an adhesion promoting film and a porous film consisting of a semiconductor impregnated with at least one ion or electron conducting agent such as an electrolyte. Said semiconductor film is deposited in the form of a paste consisting, for example, of nanocrystalline titanium oxide, water and/or ethanol, and being stabilised by a stabilising agent containing no non-volatile organic compounds. The resulting deposit is dried then sintered at a temperature below 200 DEG C. The counter-electrode (12) consists of a flexible substrate, an electrically conductive film, a catalyst and a sealing frame (21). Both electrodes are adhered then the cells are cut out and cleaned. |
