Fuel cell high-potential prevention control system |
摘要 |
A fuel cell system capable of providing a suitable power distribution is provided. A fuel cell system includes: a fuel cell that generates electric power through an electrochemical reaction between a fuel gas and an oxidant gas; a motor that can be driven upon the supply of electric power and can generate regenerative power; a power storage unit which can be charged with power generated from the fuel cell and regenerative power of the motor and can discharge charge power to the motor; an auxiliary apparatus used for operating at least the fuel cell; and a control unit that controls a power distribution between the above components. The control unit determines the power distribution using a power generation command value based on power required to be generated during a normal operation, while the control unit determines the power distribution using a power generation measured value of the fuel cell instead of the power generation command value during a high-potential prevention control that avoids a voltage of the fuel cell becoming equal to or higher than a predetermined high-potential prevention voltage threshold lower than an open circuit voltage of the fuel cell.
