Serious interest in fuel cells did not begin until the 1960's, when they were used as power for man's
first missions to the moon. Although fuel cells still provide electricity and water for today's space
missions, this unique technology is now aimed at promoting a global transition to renewable energy
sources. Fuel cell cars that use hydrogen as fuel are called "zero emission vehicles." If fuel cell cars
were to use hydrogen produced by renewable sources of energy such as solar or wind power, our
fuel supply would be unlimited - and consumption of hydrogen through fuel cells would not create any
waste nor air pollution.
Inside the H-racer is a Proton Exchange Membrane (PEM) fuel cell (see section 2, List of parts and
components - part E). It generates electrical energy by consuming hydrogen located in the on-board
hydrogen storage tank (see section 2, List of parts and components, part C), which reacts with
oxygen from the air. If you look underneath the chassis of your fully assembled H-racer, you will see
the fuel cell has air inlets that allow oxygen from our atmosphere to enter the fuel cell (Hydrogen
reaches the fuel cell from the opposite side). This fuel cell configuration is also called an
"air-breathing" hydrogen/air fuel cell, absorbing oxygen from the air - as if it was "breathing".
