Single cell structure for fuel cell

A single cell structure for a fuel cell, comprising:

• a framed membrane electrode assembly comprising a membrane electrode assembly and a frame supporting an outer periphery of the membrane electrode assembly;
• a pair of separators disposed on both sides of the framed membrane electrode assembly;
• a gas channel portion which is formed between one of the pair of separators and the membrane electrode assembly, and to which gas is supplied;
• a manifold portion having a hole that penetrates the frame and the pair of separators in a stacking direction;
• a protrusion that protrudes from at least one of the pair of separators toward the framed membrane electrode assembly to support the frame near the manifold portion;
• an extended portion of the frame that extends toward the manifold portion beyond the protrusion;
• and
• a gas flowing portion that is formed at the extended portion to supply the gas from the manifold portion to the gas channel portion,
• wherein the gas flowing portion comprises a bump that is disposed at the extended portion.
