| 摘要 |
A direct-methanol fuel cell system includes a power generating unit, a fuel container which is connected to the power generating unit and contains a first fuel being a methanol aqueous solution, a replenishing container which is connected to the fuel container and contains a second fuel which is methanol or a methanol aqueous solution having a concentration higher than a concentration of the first fuel, and a control unit configured to reduce a concentration of the first fuel and a voltage of the power generating unit until a temperature of the power generating unit rises to a preset temperature value.
