<p>PURPOSE:To inexpensively produce the electrochemical cell which is small in size and has good efficiency by constituting an electric cell having an ion exchange membrane for removing the moisture contained in gas of a pair of porous electrodes, the ion exchange membrane of a large surface area interposed therebetween and a DC power source. CONSTITUTION:A proton conductive solid electrolyte, such as anion exchange membrane consisting of a fluoroplastic system, etc., is interposed between a pair of the porous electrodes and a DC voltage is impressed between the two porous electrodes to decompose the H2O in the atmosphere to oxygen molecules and hydrogen ions and to remove the moisture (H2O) at the boundary between the porous electrodes electrified positive and the proton conductive solid electrolyte. Vertical grooves 12 and horizontal grooves 13 are formed to the proton conductive solid electrolyte 11 as the ion exchange membrane to be used to the range of about 1/2 depth of the electrolyte 11 or holes 22 of various shapes are formed thereon to greatly increase the surface area thereof, by which the reaction area is increased. The small-sized electrochemical cell which necessitates the use of the costly proton conductive solid electrolyte 11 in a smaller amt. and has good efficiency is thus produced.</p> |
