Fuel and cells
Fuel cells can be used to extract power either from natural fuels or from synthesized fuels ( mainly electrolytic hydrogen ) and so can be viewed as either generation systems or storage systems depending on their use.
Fuel cells are different from batteries in that they require a constant source of fuel and oxygen to run, but they can produce electricity continually for as long as these inputs are supplied.
Fuel cells are used for primary and backup power for commercial, industrial and residential buildings and in remote or inaccessible areas.
In addition, molten carbonate and solid oxide fuel cells using natural gas, such as the Fuel Cell Energy Co, VERSA power Co. and Bloom Energy Server, have recently become a distributed energy resource.
* Fuel cells, solar panels, or batteries to provide electrical power to the spacecraft ( batteries are also used in the crew capsule )
Fuel cells are more expensive to produce than common internal combustion engines, but are becoming cheaper as new technologies and production systems develop.
Fuel cells require high-purity hydrogen because the impurities would quickly degrade the life of the fuel cell stack.
Fuel cells are much more efficient than internal combustion engines, and produce no harmful emissions.
Fuel cells are characterized by their electrolyte material ; the SOFC has a solid oxide or ceramic, electrolyte.
