After creating hydrogen from the solar PV, the hydrogen car was designed and built without using conventional batteries. The fabrication of the car began by calculating the potential voltage and current required to power the remote control car. It was determined that the car would power at 6 volts and 2 amps. These calculations helped to
determine that a fuel cell which generates at least 12 watts of power was needed. Horizon Fuel Cell Technologies12 in Singapore had exactly what the design required and was able to ship the hydrogen fuel cell kit at a short notice. The current-voltage (I-V) characteristics of the fuel cell are shown in Figure 2.
