Abstract
A fuel supply system with a short response time is proposed. The time lag occurs when the fuel passes some processes to generate hydrogen. The system of hydrogen generation and the supply system were designed by investigating the time lag in order to obtain the necessary amount of hydrogen corresponding to the gas pedal. When the gas pedal is pressed, the motor rotates with the electric power of the fuel cell and the battery. Then, the voltage of the battery lowers, and the signal to generate more hydrogen is sent to the flow controller. So the vaporizer and the reformer are heated based on the signal. Furthermore, the signal is fed back to thermo controllers, if the supplied fuel has not reached the proper temperature.
