Controlling or regulating method for fuel cell vehicle, involves receiving reference engine output power corresponding to opening level of gas operating device and operations of DC converters are controlled or regulated

摘要

The method involves receiving a reference-engine output power corresponding to an opening level (AC) of a gas operating device. The operations of DC-converters (12,14) are controlled/regulated, such that an output voltage of fuel cell system is same or larger than a predetermined voltage, which is necessary for securing a desired engine output power, when reference-engine output power is larger than a predetermined reference value of the output power. The reaction gases are received by fuel cell (13) and carries out electro-chemical reactions for generation of electric energy. An energy storage unit (11) is charged with electric energy generated by the fuel cell and regeneration energy of the engine (16). A DC (direct current)-converter (12) provided between the energy storage unit and the engine control/regulation unit (15).
