Abstract
An electrochemical single battery such as fuel cells, and so forth, having an increased reaction area to augment its output density, which comprises a pair of electrode parts which are mutually opposed to be the electrodes when the electrochemical reaction is effected; reaction layers to carry out the electrochemical reaction, which are positioned between these two electrode parts, each being protruded alternately in one and the same direction from one electrode part toward the other electrode part in confrontation thereto, and being a slant with respect to said electrode parts; and an electrolyte layer interposed between these confronted reaction layers and holding therein an electrolyte which transmits ions to be produced at the time of the electrochemical reaction. A method for producing an electrochemical single battery, which comprises steps of: forming, on both surfaces of a planar electrolyte layer sheet, reaction layer sheets of a size smaller than the electrolyte layer sheet in lamination, followed by shaping the laminated sheets into the form of bellows; and pressing the laminated sheets in the form of bellows from a slant direction with respect to the sheet surface.
