How Do Hydrogen Cars Work?

Hydrogen is the smallest and most plentiful element in the universe. Even though it isn’t the most abundant gas in the Earth’s atmosphere, it can be found in a variety of places. It is because of this abundance that makes hydrogen-powered vehicles an appealing form of transportation. Hydrogen vehicles, such as the new Toyota Mirai, bring up the very important question: How do hydrogen cars work?

Hydrogen is naturally highly reactive and combines with almost anything, so hydrogen vehicles have the capability of extracting pure hydrogen from specific chemical compounds. This can be done in a number of ways. Once the hydrogen is extracted, it enters fuel tanks within the Mirai.

After the hydrogen is stored in tanks inside the car, it travels to the fuel cell stack, where it mingles with air coming in from the other directions, causing a chemical reaction between the hydrogen and oxygen in the air. This generates electricity, which is sent to the motor when you press on the gas pedal.

From an environmental standpoint, the best part of this is that the only exhaust product of this is plain old water, which leaves the engine through the tailpipe.

Toyota Mirai Range an EPA-Estimated 312 Miles

Because of the Toyota Mirai Range and the fact that its a hydrogen car, you may as well fill the gas pump with water.

We’ve known for a while now that the Toyota Mirai was going to be exciting, but none of the information regarding fuel efficiency and range was official—until now.

The US Environmental Protection Agency (EPA) has certified that the 2016 Toyota Mirai hydrogen fuel cell vehicle will have  with a 312-mile driving range and 67 mile per gallon equivalent (MPGe) for both city and highway driving. That means that Toyota’s original claim that the Toyota Mirai range would go at least 300 miles before needing a hydrogen refill was accurate.

These numbers are important in a market seeking clean transportation solutions. The majority of 100% electric vehicles don’t have the batteries to go very far, and even those that do still need to recharge for several hours before being good to go again. With a 312-mile driving range and 67 MPGe, the Mirai surpasses the Hyundai Tucson fuel cell’s 265 mile range and 50 MPGe. It even passes the Tesla Model S 85D’s 270 mile range!
