The invention relates to a double-source trolley bus and an isolated power supply system thereof. The isolated power supply system comprises an isolated DC/DC converter, wherein the input end of the isolated DC/DC converter is connected with a current collector, and the output end of the isolated DC/DC converter is connected with a direct current bus; an energy storing device is connected to the direct current bus; the direct current bus is also connected with a high-voltage electrical system; a fuel cell system is also connected to the input end of the isolated DC/DC converter. Because the fuel cell system is adopted as a power source, when the voltage of wires fluctuates, a power cell system of fuel cells supplies energy through the main DC/DC converter, so that the stability of an output voltage is guaranteed, and the stability of the isolated power supply system of the trolley bus is improved.
