Abstract
Official abstract text for this publication.
A fuel cell stack has a stack of cells and separators interposed between the cells. Each cell has an electrolyte membrane, an anode provided on one side of the electrolyte membrane, and a cathode provided on another side of the electrolyte membrane. The separators include a metal separator provided on an outer side of the anode and a resin separator provided on an outer side of the cathode.
First claim
Opening claim text (preview).
What is claimed is: 1 . A fuel cell stack comprising: a stack of cells; and separators interposed between the cells, wherein each cell comprises an electrolyte membrane, an anode provided on one side of the electrolyte membrane, and a cathode provided on another side of the electrolyte membrane, wherein the separators comprise an anode-side separator provided on an outer side of the anode and a cathode-side separator provided on an outer side of the cathode, and wherein the anode-side separator is a metal separator made of a metal material, and the cathode-side separator is a resin separator made of a resin material. 2 . The fuel cell stack according to claim 1 , wherein the cathode-side separator has a shape of a flat plate. 3 . The fuel cell stack according to claim 2 , wherein the anode comprises an anode-side catalyst layer provided in contact with the electrolyte membrane and an anode-side gas diffusion layer provided on an outer side of the anode-side catalyst layer, wherein the cathode comprises a cathode-side catalyst layer provided in contact with the electrolyte membrane and a cathode-side gas diffusion layer provided on an outer side of the cathode-side catalyst layer, and wherein a porosity of at least a portion of the cathode-side gas diffusion layer is higher than a porosity of the anode-side gas diffusion layer. 4 . The fuel cell stack according to claim 3 , wherein the cathode-side gas diffusion layer comprises a first diffusion layer provided in contact with the cathode-side catalyst layer and a second diffusion layer provided in contact with the first diffusion layer on a side opposite to the cathode-side catalyst layer, and wherein a porosity of the second diffusion layer is higher than a porosity of the first diffusion layer. 5 . The fuel cell stack according to claim 1 , wherein the resin material is electrically conductive. 6 . The fuel cell stack according to claim 2 , wherein the resin material is electrically conductive. 7 . The fuel cell stack according to claim 3 , wherein the resin material is electrically conductive. 8 . The fuel cell stack according to claim 4 , wherein the resin material is electrically conductive.
