CELL STACK DEVICE, FUEL-CELL MODULE, AND FUEL-CELL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide: a cell stack device that has a gas case and achieves simplification of a manufacturing process and improvement in durability; a fuel-cell module; and a fuel-cell device.

SOLUTION: The cell stack device includes: a cell stack in which a plurality of columnar fuel cells are arranged while erecting them via each current-collector member between the respective fuel cells and are electrically connected to each other; and a gas case 9 that fixes the one-end side of the fuel cells by an insulating jointing material and supplies first reactant gas to the fuel cells. The gas case 9 has a raised part 10 in which the upper surface of the gas case is partially raised. The raised part 10 has an opening 19 for fixing the cell stack to the raised part 10 by insertion. The opening 19 and the fuel cells 3 are joined by the insulating jointing material, thereby simplifying the manufacturing process of the cell stack device and achieving the cell stack device with improved durability.
