摘要： Electric power generation is properly controlled during a high potential avoidance operation. A fuel cell system comprises a fuel cell for generating an electric power upon receiving supply of a reactant gas and a controller for performing control for high potential avoidance with the upper limit of the output voltage of the fuel cell as a high potential avoidance voltage lower than the open end voltage thereof. The controller computes a larger system requirement power out of a system requirement power calculated from a load requirement and a system requirement power calculated from the high potential avoidance voltage as a system requirement power for the fuel cell. To compute the system requirement power for the fuel cell, not only the system requirement power calculated from the load requirement but also the system requirement power calculated from the high potential avoidance voltage are taken into account, and therefore the electric power can be stably generated without causing fuel shortage. The amount of the electric power to be generated can be properly controlled, and hence battery overcharging can be thus prevented.

摘要： A fuel cell system performs control such that when a power requirement for the fuel cell is lower than a predetermined value, a supply of a reaction gas to a fuel cell is stopped to keep an output voltage from the fuel cell equal to a high-potential avoidance voltage that is lower than an open end voltage. The fuel cell system further controls the output voltage from the fuel cell with the high-potential avoidance voltage set to be an upper limit when the power requirement for the fuel cell is equal to or higher than a predetermined value. By setting the upper limit of the output voltage of the fuel cell to be the high-potential avoidance voltage, which is lower than the open end voltage, the catalyst can be inhibited from being degraded by an increase in the output voltage from the fuel cell up to the open end voltage.

摘要： A fuel cell system includes a fuel cell, a secondary cell, and a control portion that controls the amount of electricity generated when the fuel cell is started. A start-time target voltage is set so as to avoid the overcharged state of the secondary cell. A voltage adjustment portion that adjusts the output voltage of the fuel cell between an open-circuit voltage and a high-potential-avoiding voltage adjusts the amount of electricity generated at the time of starting the fuel cell, on the basis of the start-time target voltage.

摘要： The oxidizing gas supply is stopped during the catalyst activation treatment, and the output voltage of the fuel cell is linearly decreased toward the reduction target voltage. Once the interruption condition of the activation treatment has been satisfied, a voltage command value of the converter is returned to a standby voltage and, after waiting till the output voltage of the fuel cell returns to the vicinity of the standby voltage, the compressor is operated to start the supply of the oxidizing gas, and the catalyst activation treatment is completed. As a result, overcharging of the battery caused by rapid increase in the output power of the fuel cell is avoided.
