Students from 12 high schools triple the number on hand for last year's inaugural event gathered on campus Tuesday for the second annual Fuel Cell Challenge, piloting vehicles powered by the separation of water into hydrogen and oxygen. Students took a written exam, then put their fuel-cell-powered vehicles through a battery of seven performance tests in the college's Field House: engineering design, artistic design, fastest car, hill climb, load pull, fuel management and longest distance. A cross-curricular assortment of faculty judged the various competitions, which attracted students from Easton Area, Hamburg Area, Liberty, Middletown, New Oxford, Northern Lebanon, Plum, Pottsville Area, Wallenpaupack Area and Williamson high schools, as well as the Warren County Career Center and the Jefferson County-DuBois Area Vocational-Technical School.
