An ECU is applied to a hybrid vehicle that is equipped with an internal combustion engine and a second motor-generator, which are configured to output a driving force for running. The hybrid vehicle is configured to run with the internal combustion engine in intermittent operation. Also, the ECU is configured to calculate an amount of dilution water that is mixed into oil in the internal combustion engine to dilute the oil. The ECU is configured to operate the internal combustion engine when the amount of the dilution water becomes larger than a first threshold.

Control apparatus and control method for hybrid vehicle

A fuel cell system includes a fuel cell, anode gas pressure adjusting means that adjusts the pressure of an anode gas supplied to the fuel cell, and cathode gas pressure adjusting means that adjusts the pressure of a cathode gas supplied to the fuel cell. The system further includes pressure control means that sets the pressure of the anode gas that is supplied when starting the fuel cell higher than the pressure of the anode gas that is supplied during power generation in the fuel cell, and controls the anode gas pressure adjusting means and the cathode gas pressure adjusting means so that a cathode gas pressure increase is started in accordance with the start of an anode gas pressure increase when the pressure of the anode gas is increased to the set pressure.
