A fuel cell includes a membrane electrode assembly 1 in which an oxidant electrode and a fuel electrode are disposed on the respective sides of an electrolyte layer. The fuel cell includes a vibrating plate 32 which generates an acoustic wave, and which is disposed so as to face the oxidant electrode with a flow path 30 for a gas formed between the vibrating plate and the oxidant electrode. The vibrating plate 32 is formed to have at least one hole 34. Moreover, the gas is transferred by acoustic streaming that occurs in the flow path for the gas 30 due to vibration of the vibrating plate 32 and reflection on a surface of the oxidant electrode facing the vibrating plate 32. |
