Abstract:
A solid polyelectrolytic module comprising a plurality of solid polyelectrolytic elements stacked so as to constitute an air path between two adjacent solid polyelectrolytic elements in a state where spacers which at least a part thereof serves as conductive contact regions are interposed therebetween, respectively, each of said solid polyelectrolytic elements being formed by thermocompression bonding of porous electrodes with the both surfaces of a hydrogen ion conductive solid polyelectrolyte membrane, respectively;wherein said plurality of stacked solid polyelectrolytic elements are electrically connected to each other in series in such manner that one porous electrode of each of said solid polyelectrolytic elements is electrically connected to one porous electrode of a solid polyelectrolytic element adjacent thereto on one side via said conductive contact region of said spacer, and the other porous electrode of each of said solid polyelectrolytic elements is electrically connected to the other porous electrode of a solid polyelectrolytic element adjacent thereto on the other side via said conductive region of said spacer; andwherein said air paths formed between said solid polyelectrolytic elements adjacent to each other have a configuration such that an air flow along an anodic surface and an air flow along the cathodic surface are separately and independently formed upon feeding of a DC voltage to a space between one porous electrode of the solid polyelectrolytic element arranged at one end of said plurality of solid polyelectrolytic elements and the other porous electrode of the solid polyelectrolytic element arranged at the other end of said plurality of solid polyelectrolytic elements.
