With a small blue crane, four researchers hoist a cylindrical fuel cell, which looks like a stack of flattened silver and gold soda cans bundled together, into the air and lower it into a rectangular cart on wheels. A tangle of tubes and wires spiral away from the system, where nearly 270 sensors and 1,000 components are nestled inside.
“It’s a behemoth; it’s a researcher’s dream,” said Dr. Kerrigan Cain, lead engineer for the team at NASA’s Glenn Research Center in Cleveland preparing to test this technology, known as a regenerative fuel cell system, over the next few months.
The system, about as long as a sedan and as tall as a person, operates like a rechargeable battery and could revolutionize the way NASA stores energy during future Moon missions through the Artemis program. When power is needed, it’s designed to combine hydrogen and oxygen gas into water, heat, and electricity, and then “recharge” by splitting the water back into hydrogen and oxygen — all on the lunar surface.
“It is an ideal technology for habitats, exploration with rovers, and many of the systems that are envisioned under Artemis,” Cain said. “Developing a sustainable, long-term human presence on the Moon requires power and energy storage solutions that fit …
