PROBLEM TO BE SOLVED: To provide a cell stack which prevents power generation output from being reduced by oxidation of a conductive member, a module and a module housing device.SOLUTION: A cell stack 18 comprises a plurality of cells 1 having a length direction and a conductive member 9 which is disposed between the plurality of cells 1 and extends in the length direction of the cells 1. The conductive member 9 includes: a plurality of conductive pieces 9a and 9b which are connected to the cell 1 via a conductive junction material 13; and coupling parts 9c and 9d which couple one-side ends of the plurality of conductive pieces 9a and 9b with each other and extend in the length direction. In the conductive member 9, a first projection 9A is provided in the conductive pieces 9a and 9b or the coupling parts 9c and 9d in a distal end in the length direction, a second projection 9B extending towards the cell 1 is provided in the conductive pieces 9a and 9b or the coupling parts 9c and 9d in any portion other than the distal end in the length direction, and the first projection 9A is longer than the second projection 9B.SELECTED DRAWING: Figure 5 【課題】導電部材の酸化による発電出力の低下を抑制させたセルスタック、モジュールおよびモジュール収容装置を提供する。【解決手段】長さ方向を有する複数のセル１と、複数のセル１間に配置され、セル１の長さ方向に沿って延びている導電部材９と、を備えるセルスタック１８であって、導電部材９は、セル１に導電性接合材１３を介して接続される複数の導電片９ａ、９ｂと、複数の導電片９ａ、９ｂの一端同士を連結しており長さ方向に延びている連結部９ｃ、９ｄとを有しており、導電部材９は、長さ方向の先端における導電片９ａ、９ｂまたは連結部９ｃ、９ｄに第１凸部９Ａが設けられており、長さ方向の先端以外における導電片９ａ、９ｂまたは連結部９ｃ、９ｄに、セル１に向かって延びる第２凸部９Ｂが設けられており、第１凸部９Ａは、第２凸部９Ｂより長くなっている。【選択図】図５
