PURPOSE:To accelerate the responsiveness of a power generating system when a load is quickly increased by providing a liquid fuel feeding device spraying and injecting liquid fuel into reformed gas. CONSTITUTION:This system has a fuel reformer 1, a high-temperature CO transformer 2, a low-temperature CO transformer 3, a phosphate type fuel cell main body 5, a liquid fuel storage tank 25, and a valve opening arithmetic unit 29. A liquid fuel feeding device is provided which is connected on the downstream side of the fuel reformer 1 of a fuel gas system and near the inlet of the CO transformer 2 and sprays and injects liquid fuel into reformed gas when the load 24 of the cell main body 5 is quickly increased. The liquid fuel injected into the reformed gas near the inlet of the CO transformer 2 when the load is quickly increased is immediately gasified due to the high-temperature reformed gas and constituting members, it is then reacted with the steam remaining in the reformed gas to generate hydrogen by the catalyst action in the CO transformer 2. The response of the power generating system to the quick increase of the load can be shortened to the inherent response of the cell main body. |
