Which statement is true about a fuel cell electric vehicle?

• A. uses hydrogen as its fuel
• B. emits nothing from its tail pipe
• C. does not have a tail pipe
• D. recharges by plugging into a charging station

Answer: (A)

Fuel cell electric vehicles generate electricity on-board by converting hydrogen stored on the vehicle into electrical energy with a fuel cell stack. The hydrogen reacts with oxygen to power the motor, and the primary exhaust is water vapor. That makes using hydrogen as the fuel the true statement. While the vehicle does emit only water vapor, saying it “emits nothing” can be misleading, since there is a water vapor emission from the tailpipe. The vehicle does have a tailpipe for that vapor. Also, energy is replenished by refueling hydrogen at stations, not by plugging in to recharge. So, the defining truth is that hydrogen is the fuel used to produce electricity on the vehicle.
