| 摘要 |
A fuel cell (10) has a fuel electrode, an air electrode, an electrolyte film (15) held between the fuel electrode and the air electrode, a liquid fuel tank (21) for containing liquid fuel, and a gas-liquid separation film (22) provided between the liquid fuel tank (21) and the fuel electrode. The gas-liquid separation film (22) exchanges heat between water vapor diffused from the fuel cell and the liquid fuel (F) and allows a vaporized component of the liquid fuel (F) to pass to the fuel electrode side.
