Regenerative fuel cells, with high round-trip efficiencies like that produced with a catalyst developed in the lab of Vijay Ramani, are well suited for submersibles, drones, and spacecraft, as well as for off-grid energy storage. (Submersible rendering image: Shutterstock)

The key is the ‘bifunctionality index’
A team has developed a catalyst that can be used to both generate fuel and provide power. A single device that both generates fuel and oxidant from water and, when a switch is flipped, converts the fuel and oxygen into electricity and water, has a host of benefits for terrestrial, space and military applications...
