Fuel cell and fuel cell stack

A fuel cell, comprising:

• a membrane electrode assembly;
• a resin frame placed around a power generation portion of the membrane electrode assembly;
• a pair of separators arranged across the membrane electrode assembly and the resin frame placed therebetween;
• a manifold portion provided in periphery of the power generation portion and configured to cause an exhaust gas discharged from the power generation portion to be flowed out from the fuel cell;
• and
• an exhaust gas flow path configured by at least one of the pair of separators and the resin frame to introduce the exhaust gas from the power generation portion to the manifold portion, wherein
• the exhaust gas flow path comprises:
• a first flow path portion that is extended from the power generation portion in a direction toward the manifold portion;
• a second flow path portion and a third flow path portion that are extended parallel to each other on a downstream side of the first flow path portion and that have downstream ends respectively connected with the manifold portion;
• a linkage part that is connected with a downstream end of the first flow path portion, an upstream end of the second flow path portion and an upstream end of the third flow path portion;
• and
• an intersecting wall surface portion that is located on a direction side from the second flow path portion toward the third flow path portion relative to the upstream end of the second flow path portion and that is extended from the upstream end of the second flow path portion in a direction intersecting with a center axis at the upstream end of the second flow path portion, wherein
• the downstream end of the first flow path portion is located on a most upstream side in the linkage part,
• when being viewed in a center axis direction of the downstream end of the first flow path portion, the downstream end of the first flow path portion is located on the direction side from the second flow path portion toward the third flow path portion relative to the upstream end of the second flow path portion, and
• when being viewed in a direction that the pair of separators are opposed to each other across the resin frame,
• the downstream end of the first flow path is opposed to at least one of the intersecting wall surface portion and the upstream end of the third flow path portion in the center axis direction of the downstream end of the first flow path portion, and
• the intersecting wall surface portion is extended from the upstream end of the second flow path portion in a direction that intersects with a direction perpendicular to a center axis at the downstream end of the first flow path portion and that is away from the downstream end of the first flow path portion.
