The alkaline fuel cell (AFC) or hydrogen-oxygen fuel cell was designed and first demonstrated publicly by Francis Thomas Bacon in 1959. It was used as a primary source of electrical energy in the Apollo space program. [41] The cell consists of two porous carbon electrodes impregnated with a suitable catalyst such as Pt, Ag, CoO, etc.
The Honda FCX, along with the Toyota FCHV, is the world's first government-certified commercial hydrogen fuel cell vehicle. [5] [4] 2008 Honda FCX Clarity. Honda established the world's first fuel cell vehicle dealer network in 2008, and at the time was the only company able to lease hydrogen fuel cell vehicles to private customers.
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.
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 ...
As of 2020, 5,648 hydrogen fuel cell buses are in use around the world, with 93.7% of them in China. [1] A wide variety of companies are currently producing hydrogen fuel cell buses. Bus manufacturers usually work with a provider of hydrogen fuel cells to power the bus, such as Ballard Power Systems or Toyota. [3] [123]
When hydrogen is consumed in fuel cells, the only emission at the point of use is water vapour. [169] Combustion of hydrogen can lead to the thermal formation of harmful nitrogen oxides. [169] The overall lifecycle emissions of hydrogen depend on how it is produced. Nearly all of the world's current supply of hydrogen is created from fossil fuels.
Hydrogen fuel cells is a zero emission technology - a technology that would eliminate air toxics, criteria pollutants that create urban smog, and global gas pollutants such as carbon dioxide. Hydrogen can be created from multiple sources - from a range of fossil fuels and from cleaner 'electrolytic process'.
