(CN1244257-A)      An electrochemical cell comprises a 1st sheet member (2) including a gas permeable section supporting one or more planar electrodes (4,6,8) sealed around the periphery with a 2nd sheet member (12) to form a reservoir (14) containing electrolyte (10). Electrical connections (41,61,81) extend from each of the electrodes through the sealed periphery (2) for external connection.    Also claimed is an electrochemical cell assembly comprising the cells described and above and including a manifold to direct 1st and 2nd gases to each section for contact with 1st and 2nd sheet members.    USE -   The cells are used for gas sensors and fuel cells.    ADVANTAGE -   The cell construction is very simple and economical. It can be produced as very thin assemblies in a variety of shapes so allowing e.g. disposable sensors. The production and assembly can be simplified so reducing costs.
