SINGLE CELL STRUCTURE FOR FUEL CELL

A single cell structure for a fuel cell includes: a framed 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 separator 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. The gas flowing portion includes a bump that is disposed at the extended portion of the frame.
