Abstract
Official abstract text for this publication.
A fuel cell includes a MEA that includes a cathode, an anode, and a solid electrolyte layer disposed between the cathode and the anode, the solid electrolyte layer containing an ion-conducting solid oxide; at least one first porous metal body adjacent to at least one of the cathode and the anode and having a three-dimensional mesh-like skeleton; a second porous metal body stacked to be adjacent to the first porous metal body and having a three-dimensional mesh-like skeleton; and an interconnector adjacent to the second porous metal body. The first porous metal body has a pore size smaller than a pore size of the second porous metal body.

1 . A fuel cell comprising: a MEA that includes a cathode, an anode, and a solid electrolyte layer disposed between the cathode and the anode, the solid electrolyte layer containing an ion-conducting solid oxide; at least one first porous metal body adjacent to at least one of the cathode and the anode and having a three-dimensional mesh-like skeleton; a second porous metal body stacked to be adjacent to the first porous metal body and having a three-dimensional mesh-like skeleton; and an interconnector adjacent to the second porous metal body, wherein the first porous metal body has a pore size smaller than a pore size of the second porous metal body. 2 . The fuel cell according to claim 1 , wherein: the first porous metal body and the second porous metal body are bonded, and in the bonded portion, the skeleton of the first porous metal body and the skeleton of the second porous metal body are entangled. 3 . The fuel cell according to claim 1 , wherein the first porous metal body and the second porous metal body both have a porosity of 85 vol % or more. 4 . The fuel cell according to claim 1 , wherein the first porous metal body has a pore size of 100 to 1000 μm. 5 . The fuel cell according to claim 1 , comprising the first porous metal body adjacent to at least the anode. 6 . The fuel cell according to claim 1 , wherein a ratio of the pore size of the first porous metal body to the pore size of the second porous metal body is 0.05 to 0.8. 7 . The fuel cell according to claim 1 , wherein the second porous metal body has a specific surface area of 100 to 9000 m 2 /m 3 . 8 . The fuel cell according to claim 1 , wherein the second porous metal body has a thickness of 0.1 to 0.5 mm.
