On global and national scales the current amount of energy generated and consumed annually, mostly from carbon-based sources, is mind-boggling. As demand will continue to increase, it is apparent that developing carbon-neutral alternative energy sources, namely solar and hydrogen gas, is an important scientific and technological challenge facing humanity this century. In this presentation the author will describe energy-related lab activities carried out by second semester freshmen general chemistry students. The labs use solar PEM hydrogen-oxygen fuel cells and are conducted outside. PEM stands for Proton Exchange Membrane. Specifically, students determine the rate of hydrogen gas production from the fuel cell's electrolyzer as a function of incident solar energy. Students then use the data to compute the amount of water and power required annually to produce enough molecular hydrogen to displace 10% of the U.S. vehicular gasoline fleet and also the subsequent savings in carbon dioxide gas emissions. If time permits, the presenter will discuss other solar fuel cell activities in development. The author gratefully acknowledges the financial support of the National Science Foundation (DUE-0736746, Course Curriculum Laboratory Improvement) for procurement of the solar fuel cell equipment.
