2. What is a fuel cell and how does it work A fuel cell is a device that can convert hydrogen to usable electric power The fuel cell is an assembly of advanced material layers where hydrogen and oxygen react with each other to generate electricity and water without any combustion Electric Circuit 40 60 Efficiency mia eO eO f eO gt i O O en S Oxygen Fuel H Hydrogen SONE eo om 2H am Heat Used Fuel Recirculates gt Air Water Vapor Flow Field Plate ag Flow Field Plate Gas Diffusion Electrode Cathode Catalyst _ Catalyst Gas Diffusion Electrode Anode Proton Exchange Membrane 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
