摘要： A fuel cell system capable of adequately controlling the water content of a fuel cell is provided. An impedance reference value is stored in a memory for an impedance comparator. The impedance reference value is a reference value that is set in order to prevent the water content in a fuel cell from decreasing too much. The impedance comparator compares a measured impedance value supplied from an impedance operation unit with the impedance reference value and performs scavenging control based on the comparison result.

摘要： Provided is a fuel cell system which can accurately detect the water state of a fuel cell to appropriately control the water content of the fuel cell. Based on an FC outlet temperature detected by a temperature sensor, an FC outlet temperature change speed detection unit detects an FC outlet temperature change speed for a unit time. If the FC outlet temperature change speed detection unit judges that the detected FC outlet temperature change speed is lower than a change speed reference value stored in a memory, an impedance measurement instruction is transmitted to an impedance calculation unit. On receiving the impedance measurement instruction from the FC outlet temperature change speed detection unit, the impedance calculation unit performs the impedance measurement for the second time. In consequence, it is possible to realize such scavenging control as to keep the water content of a fuel cell at an appropriate level by the minimum number of impedance measurement times (e.g., twice).

摘要： A moisture sensor working to measure a moisture content of a specified measurement gas is provided which consists of an electrochemical cell having a first electrode exposed to the measurement gas and a second electrode exposed to a reference gas and a controller. The electrochemical cell outputs an electrical energy arising from chemical reaction of the measurement gas with the reference gas. The controller controls at least one of voltage appearing across and current flowing through the electrochemical cell and uses one of them to measure the moisture content of the measurement gas. This enables the moisture content to be determined free from the humidify of the measurement gas.

摘要： A fuel cell system includes a heat-generation amount detection device for detecting a heat generation amount in a fuel cell, and an evaporation amount controller for controlling an evaporation amount of water in the fuel cell based on the detected heat generation amount. The heat generation amount is detected based on an output electric power of the fuel cell, an output current thereof or a temperature thereof. The evaporation amount of water in the fuel cell is controlled by adjusting at least one humidification amount of hydrogen and oxygen to be supplied to the fuel cell, or by adjusting at least one flow amount of hydrogen and oxygen to be supplied to the fuel cell.

摘要： Power generated by an engine is inputted to a carrier of a first planetary gear mechanism. Power generated by a motor is inputted to a sun gear of a second planetary gear mechanism. Power from a ring gear of the first planetary gear mechanism and power from a carrier of the second planetary gear mechanism are combined and transmitted to an axle of driving wheels. While power input from the engine to the carrier of the first planetary gear mechanism is maintained, rotation of a sun gear of the first planetary gear mechanism is restricted with a first clutch, a second clutch or a first brake. While power input from the motor to the sun gear of the second planetary gear mechanism is maintained, rotation of a ring gear of the second planetary gear mechanism is restricted with a second brake or a third clutch.
