The environmental impact of fuel cell vehicles depends on the primary energy with which the hydrogen was produced. Fuel cell vehicles are only environmentally benign when the hydrogen was produced with renewable energy. [127] If this is the case fuel cell cars may be cleaner and more efficient than fossil fuel cars.
That's the hydrogen fuel-cell vehicle, related to an EV but with specific differences that make hydrogen cars different and much rarer. To date, about 2.5 million EVs have been sold in the U.S.
The U.S. Department of Energy's Fuel Cell Technology Program states that, as of 2011, fuel cells achieved 53–59% efficiency at one-quarter power and 42–53% vehicle efficiency at full power, [106] and a durability of over 120,000 km (75,000 miles) with less than 10% degradation. [107]
This year, one new hydrogen vehicle will hit the market: the Honda CR-V e:FCEV is an adaptation of the popular compact crossover, with not only a hydrogen fuel cell (jointly developed with GM) but ...
The fuel cell has a high efficiency peak at low load, while at high load the efficiency drops. The hydrogen combustion engine has a peak at high load and can achieve similar efficiency levels as a hydrogen fuel cell. [34] From this, one can deduce that hydrogen combustion engines are a match in terms of efficiency for fuel cells for heavy duty ...
The Toyota FCHV and Honda FCX, which began leasing on December 2, 2002, became the world's first government-certified commercial hydrogen fuel cell vehicles, [16] [15] [33] and the Honda FCX Clarity, which began leasing in 2008, was the world's first hydrogen fuel cell vehicle designed for mass production rather than adapting an existing model ...
The FCHV-4 was the first fuel cell vehicle to be tested on public roads in Japan, and driving tests continued until 2004. The Clean Hydrocarbon Fuel (CHF) reformer of the FCHV-5 was equipped with a newly developed catalyst and heat exchanger to improve acceleration and fuel economy. [7] As of 2008 the FCHV-adv was available for lease in Japan. [2]
Foton Motor hydrogen fuel cell bus in Beijing, China in 2018. A fuel cell bus is a bus that uses a hydrogen fuel cell as its power source for electrically driven wheels, sometimes augmented in a hybrid fashion with batteries or a supercapacitor. The only emission from the bus is water.
