Abstract

A fuel cell includes: an anode-forming layer (820) that is provided on an outer side of one surface of an electrolyte membrane (810) and that includes an anode (820A); a cathode (830) provided on an outer side of another surface of the electrolyte membrane; a partition wall portion (825) that is formed in the anode-forming layer in the thickness direction thereof, and that divides at least a surface of the anode-forming layer remote from the electrolyte membrane into blocks, and that restrains movement of a gas between adjacent blocks; and a gas introduction portion (840) which has a gas passage portion (865) that allows the fuel gas to pass through and which introduces the fuel gas, via the gas passage portion, into the blocks divided by the partition wall portion.
