Case Study: Producing Hydrogen for Fuel Cells

Throughout this module you have considered the use of hydrogen and oxygen as reactants in the main engines of the Space Shuttle. Hydrogen and oxygen gases can also be used in fuel cells—devices that convert chemical potential energy into electrical energy. Hydrogen-oxygen fuel cells have been an essential component of the space program. The fuel cells have produced electricity to run the electronic components within spacecrafts since the 1960s. Many questions exist concerning possible sources of hydrogen for fuel cells. The lack of clear answers to these questions  has limited the large scale use of these devices.

Read “Case Study: Producing Hydrogen for Fuel Cells” on pages 297 and 298 of your textbook. Then answer “Case Study Questions” 1 to 3 on page 298. Record your answers in your Module 6: Lesson 3 Assignment. Save the copy of Lesson 3 Assignment that contains your answers to this case study and the lab to your course folder.
