Abstract

Official abstract text for this publication.

A cell stack device includes a fuel cell, a first separator and a first bonding member. The fuel cell includes a solid electrolyte and a cathode that is provided on one surface of the solid electrolyte. The first separator includes a protrusion that protrudes towards the cathode. The first bonding member bonds the cathode and the first protrusion. The thickness of a first bonding member that is positioned on an outer peripheral portion is greater than the thickness of a first bonding member that is positioned in a central portion.

First claim

Opening claim text (preview).

1 . A cell stack device comprising a fuel cell including a solid electrolyte and a cathode that is provided on one surface of the solid electrolyte, a first separator including a plurality of first protrusions that protrudes towards the cathode, and a conductive first bonding member that bonds the cathode and the plurality of first protrusions, wherein: a thickness of the first bonding member that is positioned on an outer peripheral portion is greater than a thickness of the first bonding member that is positioned in a central portion. 2 . The cell stack device according to claim 1 wherein the fuel cell further includes an anode provided on another surface of the solid electrolyte, and wherein the cell stack device further comprises a second separator including a plurality of second protrusions that protrude towards the anode, and a conductive second bonding member that bonds the anode and the plurality of second protrusions, and wherein: a thickness of the second bonding member that is positioned in a central portion is greater than a thickness of the second bonding member that is positioned in an outer peripheral portion. 3 . The cell stack device according to claim 2 wherein at least one of the first and the second bonding members is configured by a conductive ceramic. 4 . The cell stack device according to claim 1 wherein each of the first bonding members is disposed at an interval. 5 . A cell stack device comprising a fuel cell including a solid electrolyte and an anode provided on another surface of the solid electrolyte, a second separator including a plurality of second protrusions that protrudes towards the anode, and a conductive second bonding member that bonds the anode and the plurality of second protrusions, wherein: a thickness of the second bonding member that is positioned in a central portion is greater than a thickness of the second bonding member that is positioned in an outer peripheral portion. 6 . The cell stack device according to claim 5 wherein each of the second bonding members is disposed at an interval.
