Abstract
A fuel cell system whose fuel loss caused by the crossover of the fuel is small and which can be operated economically. The fuel cell system includes a fuel cell 10, a primary feeding system 12 for feeding a primary fuel which is a liquid fuel to the fuel cell 10, a secondary feeding system 13 for feeding a secondary fuel which is a liquid fuel whose saturation vapor pressure is lower than that of the primary fuel to the fuel cell 10, a ECU 30 for controlling each part so that the primary fuel in the fuel cell is replaced with the secondary fuel when terminating the operation of the fuel cell 10.
Claims6
A fuel cell system comprising:
- a fuel cell for generating electricity through an electrochemical reaction between a liquid fuel and an oxidant being fed;
- and
- a fuel cell controller for feeding a first liquid fuel to said fuel cell to make said fuel cell operate, said fuel cell controller, when terminating operation of said fuel cell, feeds a second liquid fuel saturation vapor pressure of which is lower than that of the first liquid fuel to said fuel cell, thereby replacing the first liquid fuel in said fuel cell with the second liquid fuel.
A fuel cell system comprising:
- a fuel cell for generating electricity through an electrochemical reaction in itself between a liquid fuel and an oxidant being fed;
- and
- a fuel cell controller capable of feeding plural kinds of fuels to said fuel cell, said fuel cell controller selects one fuel which corresponds to status of said fuel cell from the plural kinds of fuels and feeds the fuel to said fuel cell.
