The fuel cell single cell of the present invention includes: a membrane electrode assembly; a low-rigidity frame that supports the membrane electrode assembly; a pair of separators that holds the low-rigidity frame and the membrane electrode assembly therebetween; a gas channel for supplying gas to the membrane electrode assembly between the pair of separators; manifold parts that are formed in the low-rigidity frame and the pair of separators to supply the gas to the gas channel; restraining ribs that restrain the low-rigidity frame near the manifold parts; a projected part of the low-rigidity frame that projects toward the manifold parts beyond the restraining ribs; and a gas flow part that is formed in the projected part to supply the gas from the manifold part to the gas channel.
