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.
Extremely expensive materials were used and the fuel cells required very pure hydrogen and oxygen. Early fuel cells tended to require inconveniently high operating temperatures that were a problem in many applications. However, fuel cells were seen to be desirable due to the large amounts of fuel available (hydrogen and oxygen). [citation needed]
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 ...
Whereas the common PEM fuel cell, also called Low Temperature Proton Exchange Membrane fuel cell (LT-PEM), must usually be operated with hydrogen with high purity of more than 99.9 % the HT-PEM fuel cell is less sensitive to impurities and thus is typically operated with reformate gas with hydrogen concentration of about 50 to 75 %.
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 ...
Hydrogen fuel cells are vying for a top spot among humanity’s green energy solutions, but chemicals found in fuel cells— as well as the environmental cost of producing hydrogen—are a major ...
