Abstract
Official abstract text for this publication.
The fuel cell stack formed by arranging a terminal on both ends of a cell stacked body in which a plurality of cells including a membrane electrode assembly and separators interposing the membrane electrode assembly therebetween is stacked, includes a rust preventive plate which is arranged between a metal separator and a positive electrode terminal on a high potential side of the cell stacked body, and includes a material more noble than that of the separator in the surface.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel cell stack formed by arranging terminals on both ends of a cell stacked body in which a plurality of single cells including a membrane electrode assembly and separators interposing the membrane electrode assembly therebetween is stacked, the fuel cell stack comprising: a rust preventive plate which is arranged between the separator and the terminal on a high potential side of the cell stacked body, and includes a material more noble than that of the separator in a surface, wherein the rust preventive plate and the separator are directly contacted with each other at a peripheral edge portion of the separator and electrically connected, a cooling medium flowing through the cell stacked body is circulated inside the peripheral portion of the separator, and the rust preventative plate is disposed so as to be in contact with the cooling medium. 2. The fuel cell stack according to claim 1 , wherein the noble material has a higher conductivity and corrosion resistance than the separator. 3. The fuel cell stack according to claim 1 , wherein the noble material includes at least any one material of gold, iridium oxide, palladium oxide, and ruthenium oxide. 4. The fuel cell stack according to claim 1 , wherein a material of the rust preventive plate includes titanium. 5. The fuel cell stack according to claim 1 , wherein a material of the separator includes titanium. 6. The fuel cell stack according to claim 1 , wherein the rust preventive plate is disposed to be electrically connected to a portion on the high potential side of the cell stacked body.
