ELECTROCHEMICAL ACTOR

摘要

An electrochemical actor with a closed gas chamber has a plurality of cells (7), each of which contains a solid electrode (16) made of an electrochemically reversibly oxidisable substance and a counter-electrode (18), whereby a rise or fall in pressure convertible in one movement is effected by a reversible d.c.-generated electrochemical reaction process in the gas chamber. In order to simplify production and make it more economical and to improve its function, each cell (7) has a stackable frame-like spacer (12) of an electrically insulating and readily heat-conductive material comprising the edge (14) of a metal cell housing (13) containing a matrix (15) impregnated with electrolyte, the solid electrode (16), a separator (17) and the counter-electrode (18), with the counter-electrode (18) of each cell (7) closely stacked against the cell housing (13) of the next cell (7).
