Hybrid system for providing electrical power for fuel cell, has power supply circuit of fuel cell, which has fuel cell unit, voltage conversion unit of fuel cell and sensor unit

摘要

The hybrid system has a power supply circuit of a fuel cell (1), which has a fuel cell unit (11), a voltage conversion unit of a fuel cell (12) and a sensor unit (13). The power supply circuit of a fuel cell and the power supply circuit of a secondary battery (2) are electrically connected next to each other. The current input of the power supply circuit of a secondary battery is electrically connected with the current output of the fuel cell unit.
