HyAxiom’s 440-kilowatt phosphoric acid fuel cell is now its flagship product, and it still builds on technical know-how developed under the Apollo and space shuttle programs.NASA’s investment in fuel cells dates to the 1960s when most of the world was still reliant on fossil fuels. A fuel cell generates electricity and heat when hydrogen and oxygen bond through an electrolyte. Because its only by-product is water, it’s an environmentally friendly power source.
NASA funded development of the first practical fuel cells because they were necessary to cut weight from the Apollo spacecraft for Moon missions. Three fuel cells in the Apollo service module provided electricity for the capsule containing the astronauts. The division of Pratt & Whitney that made the fuel cells later became UTC Power, now a subsidiary of Doosan Group known as HyAxiom Inc.NASA funded three companies, including a portion of Pratt & Whitney, to develop prototypes.
“The models they built for these products we use today had a lot of the electrochemistry understanding from the space program,” said Sridhar Kanuri, HyAxiom’s chief technology officer.
