Is hydrogen propulsion the future? How does a fuel cell work? Are there any risks? In this article, a hydrogen propulsion expert from BMW will answer these questions and more.
their small size and efficient engines enable Smart cars to run on considerably less gasoline than most other vehicles, and the Smart fortwo is the most fuel efficient gasoline-powered, non-hybrid vehicle in the U.S. Given that Smart cars are made to carry, at most, two people, and that ...
The membrane allows only the hydrogen proton(质子) to pass through, forcing its electron to run around the membrane to catch up with the proton on the other side. This creates electricity, water,and heat, but no exhaust emissions.If the fuel cell is powered with pure hydrogen, it has the...
Honda's hydrogen fuel cell powertrain consists of a single motor that makes 174 horsepower and drives the front wheels. Two hydrogen tanks are mounted underneath and behind the rear seat; the fuel cell system and drive unit will be mounted under the hood. If the tanks should run out before...

Battery Electric Vehicles (BEVs):These cars run on a battery that you charge from an outside power source. Hybrid Electric Vehicles (HEVs):These vehicles have both a regular engine and an electric motor with a battery. They work together to make the car go. ...
It can drive 20–55 miles on electricity before switching to gas. Fuel Cell Electric Vehicle (FCEV): It uses hydrogen fuel cells to produce electricity. It has a 300–400 mile range and fast 5-minute refuel times. Compared to gas-powered cars, EVs are more efficient. They have lower ...
But what about electric vehicles (EVs), which run entirely on batteries? Let’s break down how EVs are impacted by cold weather — and what EV drivers can do to maximize their range. Preserving fuel economy in cold weather When it’s 20 degrees Fahrenheit outside, fuel economy is significa...
Do electric cars lose range over time? Yes, as an EV battery degrades, the vehicle’s maximum range decreases. For example, if you purchase an EV today with a 300-mile range, you would lose, on average, about 21 miles of range after five years and 45 miles after 10 years. This dec...
If you could run your car on a fuel that burned so cleanly that itsonly emissions were water vapor, you'd do it in a heartbeat, right? It turns out that you can. Automakers are developing technology that would allow us to use hydrogen instead of gasoline to fuel our cars. Hydrogen is...
