This means you only need about half the amount of hydrogen, with double the fuel economy. But because a fuel cell is more than twice as efficient as an internal combustion engine, a fuel cell car travels farther on that tank of hydrogen than a traditional car would on gasoline. Since the “engine” (i.e., fuel cell) has no moving parts, you’ll never need to change the oil. They can refuel in just a few minutes and the fueling experience is almost identical to a gas station. Similar to today’s gasoline vehicles, fuel cell electric cars can have a driving range of more than 300 miles on one tank of hydrogen fuel. Fuel cell cars are very similar to traditional gasoline powered cars. There are also no pollutants emitted from the tailpipe-just water! 4. Compared to conventional gasoline vehicles, fuel cell vehicles can even reduce carbon dioxide by up to half if the hydrogen is produced by natural gas and by 90%, if the hydrogen is produced by renewable energy, such as wind and solar. Unlike batteries, fuel cells do not run down or need to recharge-as long as there’s a constant source of fuel and oxygen. See the manual for more details on Automatic Atom Labels. ChemDraw 84C2 Turn off Automatic Atom Labels in the ChemDraw Preferences. Fuel cells are a clean way to produce power.įuel cells are similar to batteries in that they produce electricity without combustion or emissions. When I add/remove a bond in ChemDraw, hydrogens are automatically removed/added. Because fuel cells can be grid-independent, they’re also an attractive option for critical load functions such as data centers, telecommunications towers, hospitals, emergency response systems, and even military applications for national defense. These range from powering buildings, cars, trucks, to portable electronic devices and backup power systems. Hydrogen and fuel cells can be used in a broad range of applications. Explicitly draw all H atoms Should you want to restart the exercise, the drop-down menu labeled starting pointscan be used to redraw the starting molecule on the sketcher ChemDoodle starting points v H2CC CH2 Use VSEPR to predict bond angles at the marked atom. Fuel cells can be used to power several applications. Transcribed image text: Complete this structural formula by adding enough hydrogens to complete the tetra-valence of each carbon.
