Researchers have developed an innovative high-energy density chemical fuel that is capable of powering bug-sized robots. This breakthrough was made possible due to a new type of fuel cell, called a “flexible proton exchange membrane fuel cell”, that is lightweight, efficient, and relatively easy to manufacture. The fuel cell is powered by a combination of hydrogen and oxygen to generate electricity that is capable of powering a robot for up to an hour. This new type of fuel cell could revolutionize the field of robotics and open the door to robots that are even smaller and more capable than ever before. This could lead to an entirely new generation of robots, from miniature drones to tiny medical robots capable of performing vital tasks.
