CELL STACK, AND FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a cell stack capable of keeping insulation between a gas manifold and a power generation element; and to provide a fuel cell.

SOLUTION: A plurality of power generation elements each formed by laminating an inside electrode, a solid electrolyte and an outside electrode are juxtaposed on the surface of an electrically insulating porous supporting substrate having a gas passage in the inside, the inside electrode of the power generation element and the outside electrode of other power generation element adjacent to the power generation element are electrically connected, the outer peripheral surface of one end part of the porous supporting substrate is covered with an insulating dense layer different from the solid electrolyte, and the dense layer of the porous supporting substrate and a holding member are joined through an insulating seal member.
