PROBLEM TO BE SOLVED: To provide an electrolytic cell unit which has a simple structure and is capable of being miniaturized, and to provide an electrolytic cell stack device and an electrolysis apparatus.SOLUTION: The electrolytic cell unit includes: a support 2 having a columnar shape and a plurality of circulation holes 7 formed by penetrating the support from one end thereof to the other end along the longitudinal direction thereof; an electrolytic element part A which is arranged on the surface of the support 2 and obtained by successively layering a cathode 3, a solid electrolyte layer 4, and an anode 5 thereon and from which a hydrogen-containing gas is produced from a steam-containing gas; an electrolytic cell 1 obtained by arranging an interconnector 6 to be connected electrically to the electrolytic element part A; and a lid member which is arranged on the other end of the electrolytic cell and has a space to be used for circulating the fluid, which is circulated through the circulation hole, through the different circulation hole. Since a pressure loss in the space between one end side of the electrolytic cell and the other end side in the width direction is larger than 5 times of another pressure loss between an inlet and an outlet of the circulation hole, to which steam is supplied, a structure of the electrolytic cell unit can be made simpler and an electrolysis reaction can be performed efficiently therein. |
