As shown in FIG. 5, crude light naphtha stored in a fuel storage tank 50 is supplied to a reformer 51, and a steam-reformed hydrogen-rich fuel gas is supplied to the reformer 51 via a fuel gas supply pipe 52. The fuel cell was designed to be introduced into the anode 53a of the fuel cell main body 53 and used for a cell reaction.

分を必要とするのである。However, crude light naphtha supplied to a fuel cell has an extremely large number of carbon atoms as compared with natural gas which is usually used as a fuel. Steam reforming is performed at 57, but an excessive amount of water is required for the reforming reaction to be performed effectively.

雑な問題であった。[0004] However, when a fuel gas reformed by using excess water is supplied to the anode 53a of the fuel cell, the concentration of hydrogen used in the cell reaction is reduced due to the high partial pressure of water vapor of the fuel gas, thereby generating power. There is a problem that the efficiency is reduced. Therefore, if the water supply amount is reduced in order to suppress the decrease in the hydrogen concentration, a large amount of carbon is turned out in the reformed fuel gas, and the turned out carbon scatters in the fuel gas supply pipe. To close the supply passage. As a result, the supply of the fuel gas becomes impossible. Therefore, in order to remove the carbon blocking the supply passage, it is necessary to stop the operation of the fuel cell and clean the fuel gas supply pipe each time, which is inefficient and complicated. It was a problem.

When the pressure loss in the fuel gas supply pipe increases,
By stopping the flow of the fuel gas in the fuel gas supply pipe and injecting air from the fluid injection path, the accumulated precipitate is chemically burned and discharged from the discharge path, thereby accumulating in the fuel gas supply pipe. The deposited precipitate can be easily removed. Moreover, even when one system of the plurality of fuel gas supply pipes is closed, the supply of the fuel gas can be continued using another fuel gas supply pipe, so that the fuel cell can be operated without stopping the operation of the fuel cell. Precipitates in the gas supply pipe can be removed. Further, even during a normal operation, the fuel gas supply amount to the fuel cell is adjusted by setting all of the plurality of fuel gas supply pipes in a flow state or a part of the plurality of fuel gas supply pipes in a closed state by a switch, thereby generating power of the fuel cell. Efficiency can be controlled. In addition, the molten carbon
Air is distributed from the air supply channel that supplies air to the salt fuel cell
Therefore, the device that injects air from the fluid injection path to remove the precipitate can also be used as the device that supplies air to the molten carbonate fuel cell. Therefore, it is possible to simplify the system configuration and improve the energy efficiency of the entire apparatus.
