Abstract
Official abstract text for this publication.
A fuel cell includes: a membrane electrode assembly; a gas flow path member that has a first side that is arranged on a surface of the membrane electrode assembly: a pair of separators that are arranged sandwiching the membrane electrode assembly and the gas flow path member, and each have a separating portion and a plurality of holes separated by the separating portion, the holes being provided in each of opposite sides of the separator and being lined up in a predetermined direction along the sides; and a sealing plate that is arranged on an end portion of the first side adjacent to the holes, and is welded to the gas flow path member at a predetermined welding position, the predetermined welding position being provided in a region that includes a position on a straight line that passes through the separating portion and is perpendicular to the sides.
First claim
Opening claim text (preview).
What is claimed is: 1 . A fuel cell comprising: a membrane electrode assembly; a gas flow path member that has a first side that is arranged on a surface of the membrane electrode assembly; a pair of separators that are arranged sandwiching the membrane electrode assembly and the gas flow path member, and that each have a separating portion and a plurality of holes separated by the separating portion, the holes being provided in each of opposite sides of the separator and being lined up in a predetermined direction along the sides; and a sealing plate that is arranged on an end portion of the first side adjacent to the holes, and is welded to the gas flow path member at a predetermined welding position, the predetermined welding position being provided in a region that includes a position on a straight line that passes through the separating portion, and the straight line being perpendicular to the sides. 2 . The fuel cell according to claim 1 , wherein the predetermined welding position has a region that overlaps with the straight line that passes through the separating portion and is perpendicular to the sides. 3 . The fuel cell according to claim 1 , wherein the separating portion is provided in a direction perpendicular to the opposite sides of the separator. 4 . The fuel cell according to claim 1 , wherein the gas flow path member is larger than a power generating region of the membrane electrode assembly in the predetermined direction, and the predetermined welding position is closer to the holes than an end portion on a hole side of the power generating region is. 5 . The fuel cell according to claim 1 , wherein the number of the predetermined welding position ranges from one to six. 6 . The fuel cell according to claim 5 , wherein the number of the predetermined welding position is three.
