The fuel cells made at this time were most similar to today's phosphoric acid fuel cells. [1] Most hydrogen fuel cells today are of the proton exchange membrane (PEM) type. A PEM converts the chemical energy released during the electrochemical reaction of hydrogen and oxygen into electrical energy.
Demonstration model of a direct methanol fuel cell (black layered cube) in its enclosure Scheme of a proton-conducting fuel cell. A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) [1] into electricity through a pair of redox reactions. [2]
Formic acid-based fuel cells represent a promising energy supply system in terms of high volumetric energy density, theoretical energy efficiency, and theoretical open-circuit voltage. They are also able to overcome certain problems inherent to traditional hydrogen (H 2) feed fuel cells such as safe handling, storage, and H 2 transportation.
It manufactures and markets solid oxide fuel cells that produce electricity on-site. The company was founded in 2001 and came out of stealth mode in 2010. It raised more than $1 billion in venture capital funding before going public in 2018. Its fuel cells are subsidized by government incentive programs for green energy.
STS-83 was a NASA Space Shuttle mission flown by Columbia.It was a science research mission that achieved orbit successfully, but the planned duration was a failure due to a technical problem with a fuel cell that resulted in the abort of the 15 day duration.
A fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen.
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%.
UTC Power was a fuel cell company based in South Windsor, Connecticut. It was part of United Technologies Corporation; it was purchased by ClearEdge Power in February 2013. The company specialized in fuel cells for buildings, [1] buses [2] and automobiles. [3] It has also developed fuel cells for space [4] and submarine applications in the past.
