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 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%.
The planar fuel cell design geometry is the typical sandwich type geometry employed by most types of fuel cells, where the electrolyte is sandwiched in between the electrodes. SOFCs can also be made in tubular geometries where either air or fuel is passed through the inside of the tube and the other gas is passed along the outside of the tube.
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.
At first solid electrodes were used in the Grove cell, Francis Thomas Bacon was the first to use gas diffusion electrodes for the Bacon fuel cell, [3] converting hydrogen and oxygen at high temperature into electricity. Over the years, gas diffusion electrodes have been adapted for various other processes like:
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 ...
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 ...
A schematic of a hydrogen fuel cell. To supply hydrogen, electrocatalytic water splitting is commonly employed. Hydrogen and oxygen can be combined through by the use of a fuel cell. In this process, the reaction is broken into two half reactions which occur at separate electrodes.
