No not nuclear fission, it is a chemical reaction which reverses the splitting of water by an electric current into hydrogen and oxygen. In Fuel Cell these two gases are brought together in an electrolyte either side of a porous membrane and fuses the gases together to make dc electricity and a by product, pure water.
Robert Groves, a 19th century cleric was first to publish this curiosity. The efficiency was hugely improved by Francis Bacon in the UK in the 1950's. He got 6 Kilowatts from his 'Bacon Cell ' prototypes and Pratt and Whitney took his designs for further development. 'Bacon Cells' were installed in the Apollo missions and provided virtually all the electrical power on the ship since oxygen and hydrogen were routine gases for NASA engineers. The water generated in the cells was drunk by the crew, reducing the weight at lift off.
When Apollo 13 suffered an explosion of an oxygen tank supplying the fuel cells the catastrophic loss of electrical power explains the failure of the Moon mission.
NASA recognised his indispensible contribution to the Moon missions and sent him a certificate of gratitude following the Apollo 11 Moon landing in 1969.
A cell: All cells divide using Binary fission (except for sex cells which use meiosis) plant cells use binary fission (that is how they grow and repair) animal cell use binary fission (also how grow and repair themselves) bacteria use binary fission (this is how they reproduce, they evolve due to genetic mutations that some times occur during binary fission). The only things that don't use this are viruses which aren't cells and aren't even considered living.
Nuclear Fission
Yes, it does so in almost all reactors
binary fission
An organism that can undergo binary fission would be a plan ol prokaryotic cell or a protozoan if you want something specific.
All the operating reactors use fission, practically all with U-235, a few with Pu-239, and sometimes with a mixed fuel (MOX)
binary fission
In breeder nuclear fission more fuel is produced than what consumed. In conventional nuclear fission less fuel is produced than what is consumed.
Binary fission
if the bomb is a fission bomb it will use uranium 235 for fuel. if the bomb is a thermonuclear bomb (fusion) it will use the element hydrogen and an isotope of hydrogen for fuel.
It must or cells would not be able to reproduce. Eukaryotic cells replicate by mitosis. Prokaryotic cells replicate via binary fission.
