About this item
| Description: | The fuel cell in a model hydrogen car is used to drive a circuit. The voltage produced by the fuel cell is monitored with a multi meter and the level of the hydrogen tank can be seen in mm by watching the change in the level of the displaced water (most easily seen on the left hand edge of the cylinder). |

Transcript:
There is no sound. When the circuit is closed, LEDs light showing current is flowing. The voltage is initially 0.676 volts and the hydrogen tank shows a level of 12 millilitres of hydrogen at a timestamp of 0 minutes and 9 seconds. At the timestamp 2 minutes and 39 seconds, the voltmeter reads 0.656 volts and there is 10 millilitres of hydrogen remaining in the tank
