Gemini 5 fuel cell assembly. As with Gemini 4, the crew had difficulty sleeping in alternate rest periods. They still had little rest when they decided to take their sleep periods together. The phantom rendezvous came on the third day. It went perfectly, even though it was the first precision maneuver on a spaceflight.
Gemini 5 (August 21–29, 1965) demonstrated the 8-day endurance necessary for an Apollo lunar mission with the first use of fuel cells to generate its electrical power. Gemini 6A accomplished the first space rendezvous with its sister craft Gemini 7 in December 1965, with Gemini 7 setting a 14-day endurance record for its flight.
PEM fuel cells were used in the NASA Gemini series of spacecraft, but they were replaced by Alkaline fuel cells in the Apollo program and in the Space Shuttle. General Electric continued working on PEM cells and in the mid-1970s developed PEM water electrolysis technology for undersea life support, leading to the US Navy Oxygen Generating Plant.
Early PEM fuel cell applications were focused within the aerospace industry. The then-higher capacity of fuel cells compared to batteries made them ideal as NASA's Project Gemini began to target longer duration space missions than had previously been attempted. [9] As of 2008, the automotive industry as well as personal and public power ...
In November 2024, Bloom Energy (NYSE: BE) made a big announcement: It will be supplying a roughly 80-megawatt fuel cell project in South Korea. The project, assuming all goes as planned, will be ...
The Gemini vehicle utilizes a carbon-fiber monocoque body with aluminum steering, motor mount, and safety harnesses fastened to the body via carbon fiber inserts. The vehicle is propelled by a 3-phase brushless hub motor modified from an electric bike. The electrical power is generated by a Horizon H-100 [6] fuel cell supplied by pure hydrogen ...
The hatch in the Gemini B spacecraft's heat shield connected to a transfer tunnel that ran through the adaptor module. This contained the cryogenic hydrogen, helium and oxygen storage tanks, and housed the environmental control system, fuel cells, and four quad reaction control system thrusters and their propellant tanks. The transfer tunnel ...
An electric car isn’t the only passenger vehicle out there that generates zero tailpipe emissions. You've probably heard of fuel cell cars.They use hydrogen gas to make electricity to power a ...
