Fuel cell

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, each of the pair of separators having:
• a plurality of holes provided in each of opposing sides of the corresponding separator and being lined up in a predetermined direction along each of the opposing sides, and
• at least one separating portion provided on each of the opposing sides so as to separate the plurality of holes, the at least one separation portion defining a region that extends generally along a straight line that is perpendicular to the opposing sides;
• and
• a sealing plate that is arranged on an end portion of the first side of the gas flow path member adjacent to the plurality of holes, and is welded to the gas flow path member at a predetermined welding position, the predetermined welding position being provided in the region defined by the at least one separating portion.
