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.
Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. [3] Fuel cells can produce electricity continuously for as long as fuel and oxygen ...
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 ...
This is a list of fuel cell vehicles (FCV), or fuel cell electric vehicles (FCEV), that use a fuel cell to power an electric drive system. For Hydrogen internal combustion engine vehicles (HICEV) see the List of hydrogen internal combustion engine vehicles .
The Toyota FCHV and Honda FCX, which began leasing on 2 December 2002, became the world's first government-certified commercial hydrogen fuel cell vehicles. [3] [4] [5] Its first commercial fuel cell vehicle was developed from the FCHV-4, which was adapted from the Toyota Highlander body. [6] "FCHV" stands for "Fuel Cell Hybrid Vehicle".
Hydrogen internal combustion engine cars are different from hydrogen fuel cell cars. The hydrogen internal combustion car is a slightly modified version of the traditional gasoline internal combustion engine car. These hydrogen engines burn fuel in the same manner that gasoline engines do; the main difference is the exhaust product.
Bio-Ethanol based fuel cells may improve the well-to-wheel balance of this biofuel because of the increased conversion rate of the fuel cell compared to the internal combustion engine. But real world figures may be only achieved in some years since the development of direct methanol and ethanol fuel cells is lagging behind hydrogen powered fuel ...
The alkaline fuel cell (AFC), also known as the Bacon fuel cell after its British inventor, Francis Thomas Bacon, is one of the most developed fuel cell technologies. Alkaline fuel cells consume hydrogen and pure oxygen, to produce potable water, heat, and electricity. They are among the most efficient fuel cells, having the potential to reach 70%.
